The American system is derived from the system historically used in Britain. Because it is "derived from" you may correctly infer that they are not identical. The smallest unit of weight in everyday use is the Avoirdupois ounce. We call it the ounce. Next up is the pound, 16 ounces. Then we jump to the ton, 2, pounds. Internationally speaking, the American ton is known as the short ton.

A hundredweight, pounds, is also used in commerce. American liquid measurements normally start with the fluid ounce, not to be confused with the ounce used in weight measurement. Increasing quantities are the pint of 16 fluid ounces, the quart of two pints, and the gallon of four quarts. A pint of water weighs about one pound. Cooks also use the cup measurement of 8 ounces. Length measurement starts with the inch, about the length of the last digit of your index finger.

Then 12 inches make a foot, three feet make a yard, and 5, feet make a mile. Troy Troy weights, named after the French city Troyes, are used for precious metals. The reason for this apparent discrepancy is that there are 16 ounces in an avoirdupois pound and only 12 ounces in a troy pound.

Unless you are a jeweler you won't often see troy weights. There is where you'll find your first confusion. The British formerly used the same names for weights and measures that we do but this is now generally illegal. A British green grocer was arrested and tried for selling bananas by the pound.

He was convicted of this heinous crime and summarily punished. Britain is a member of the European Union which has decreed metric for all members.

Britain has joined the metric club with limited exceptions to the old system. Many of the Queen's subjects are increasingly unhappy about this turn of events and want to get out of the EU. The movement is known as "Brexit" and comes up for a referendum in June Road signage is still in miles and ale is still served by the pint in British pubs, indefinitely. But, the imperial fluid ounce is smaller than an American fluid ounce.

Now you can find a trivia game and win the weights and measures category. Oops, the game is not over. When you buy your brew in a store it has to be in a metric container. An imperial pint is If the pub pint of ale ever gets outlawed you would have to order a five-sixty-eight-point-twenty-six. I guess the bar keeper will know you've had too many when you can't get all of that out of your mouth. A unique British unit of weight is the stone. People weigh themselves in stone, or at least they did before the UK went metric.

One stone is 14 pounds. Most Americans have heard that the United States is converting to the metric system. Some busy-bodies are not content with the simple units of measure that we grew up with and for various reasons they have advocated that the USA convert to the metric system.

Their rationale is that most of the rest of the world has already gone metric. I say "So what? If it ain't broke why fix it? Pounds, yards, and gallons worked for daddy so why change it? In recent years the metric advocates have succeeded in getting Congress to require metric units on many products. For the past 10 years or so all product labels now have the metric equivalent of the weight, length, or volume in parenthesis next to the good old American way of measuring things.

For example, here I have a 20 ounce gram can of sugar and a box of hand wipes 8 inches x Having those metric units on the labels is just so darn practical — not.

I know what some of you are thinking by now. But before you start accusing me of having metriphobia please be aware that I have been using both American and metric units from university days throughout my career, doing it comfortably for decades. I am a chemical engineer. In doing design calculations for chemical and gas process plants and oil refineries I must use data from laboratories.

Pump specifications must be written in gallons per minute and pipe sizes in nominal inches. Therefore, I have been converting grams-per-liter to pounds-per-gallon and doing many similar calculatons since long before electronic calculators and computers came along and made the task a bit easier. There is a gradual change taking place in this niche of technology. The change is primarily driven by American multi-national companies which want to use global standards for business purposes, not because they love metric meters and liters and grams and such.

Let the free market decide, not some political hack or government clod with nothing else to do today. On a more personal note, for many years I was the only person on my block who owned metric wrenches, feeler gauges, and such. When I was young guy I liked to do some of my own auto engine work.

My first three cars were a beige Volkswagen Beetle affectionately known as the "Bug" or the "V-Dub" , a red Karmann Ghia convertible, and a beautiful white Porsche S. I still have an open end wrench from the tool set, 8 mm on one end and 13 mm on the other.

Actualy I have two of these but I cut one in half so I could get into tighter spots in those nifty little air cooled engines. The metric system is a decimal system of weights and measures in which the gram is the unit of weight, the meter is the unit of length, and the liter is the unit of volume.

It weighs 2, pounds, pounds more than an American ton. Amounts greater or smaller than grams, meters, and liters are expressed by adding prefixes derived from Greek and Latin words for ten, hundred, and thousand. Additional prefixes are available for millions and billions but you won't see those on the store shelves, well, except in computer stores where everything is mega-, giga-, and tera- these days.

You already know that. Use the generator to make customized worksheets for conversions between measuring units. You can choose to include inches, feet, yards, miles, ounces, cups, pints, quarts, gallons, ounces, pounds, millimeters, centimeters, meters, kilometers, grams, kilograms, liters, and milliliters.

You can also make worksheets for the metric system: Extra vertical space below the problems: Group projects are included in addition to numerous individual activities. In Book 1, students learn how a linear measurement system is developed and then do activities related to measuring length.

Book 2 focuses on length, perimeter, and area measures. In Book 3, the concept of area is further developed, and students are introduced to volume. Book 4 covers a variety of topics. Give each student one canister and allow time for them to search for their "partner" - without looking into the canister.

Once the groups have found their match, the students can check their results by opening the canisters. Volume Worksheet pdf - Student worksheet that goes along with the presentation. Volume Lab pdf - This lab consists of measuring the volume of liquids and regular solids as well as using graduated cylinders and overflow cans to find the volume of irregular objects rocks.

Mystery Canisters pdf - The density lab, known as Mystery Canisters, challenges students to modify three film canisters so that they have one that floats, one that sinks, and one that will remain suspended in the tub of tap water.

Materials needed for the lab are: Students will also need equipment to help them measure mass triple-beam balance and volume graduated cylinders and overflow cans. Students are allowed a few minutes to create the three canisters that will 1 float, 2 sink, and 3 remain suspended.

Students may have difficulty getting one of the cansisters perfectly suspended. If the students can get the canister to suspend with less than half of the lid above the surface, they should get numbers that result in a density close to 1. Once the students have their canisters approved, they find the mass and volume of the canisters and calculate each density.

Reinforce the lesson with the layering liquids activity from the TerrificScience. Gummy Bear Lab pdf - This lab incorporates a variety of metric measurements length, volume, mass, and density to record what happens to a gummy bear when it is placed in a water overnight. This lab worksheet was based on a gummy bear lab available online; however, the website with the original lab is no longer available. Metric Mania Survey pdf - This worksheet is used at the end of the unit to review the material we have studied.

Metric Challenge Puzzle pdf - Students review key terms from the metric system to discover the answer to a joke. An answer key is provided. One part of my metric unit includes a few lessons related to conversions. My students have difficulty relating the English system of measurement feet, pounds, and gallons to the metric units meter, kilograms, and liters. The first lesson consists of making conversions from one system to the other.

During this lesson, students use the information from a measurement chart to convert measurements. This assignment allows my students to connect the English system of measurements used in our daily lives to the metric system units. The second lesson focuses on using a "metric ladder" to calculate conversions within the metric system. In the beginning the lesson is focused on counting the number of "jumps" it takes to move from one metric unit to another.

The "jumps" determine the number of times the decimal is moved and in which direction. I remind students to count the number of jumps it would take to move from one unit to another, such as moving from meters to millimeters, rather than counting the number of boxes.
