Stanley Units – what are they?

English Units of Measure Length Volume Weight 1 foot = 12 inches 1 gallon = 4 quarts 1 ton = 2000 pounds 1 yard = 3 feet 1 quart = 2 pints 1 pound = 16 ounces 1 mile = 5280 feet 1 pint = 2 cups 1 cup = 8 ounces The following are some commonly used units of measure. You are expected to know these.

Examples for measuring:  Give the value for each measure.

A = ______B = ______C = ______D = ______

 Locate each measure.

A = 2 3/8 in B = 3 13/16 in C = 12/16 in D = 4 ¼ in Metric Units of Measure The metric system is based on powers of ten. It is far more easily understood than our English system. One reason we may disagree is because we “grew up” with the English system. There was a time when there was a concentrated movement towards using metric, but because it met with such resistance, that effort has gone away. Kilo 1000 Hecto 100 Deka or Deca 10 Unit (meter, liter, gram) Deci 0.1 (one tenth) Centi 0.01 (one hundredth) Milli 0.001 (one thousandth) Some common conversions you should know: 1 km = ______m 1 m = ______km 1 m = ______cm 1 cm = ______m 1 m = ______mm 1 mm = ______m 1 cm = ______mm 1 mm = ______cm

The following are some metric units of measure.

Once you know and understand some basic relationships in the Metric system, finding others (converting from one unit of measure to another) can be easy; especially, if you have a TRICK.

So let’s say you have some conversions to do, but you don’t have a table handy and you’re not really sure about which one is which. Remember the following. King Henry King Henry Drinks Unsweetened Dark Chocolate Milk
