Linear Measurement 1 foot (ft)= 12 inches (in) 1 yard (yd) = 3 ft 1 yd = 36 in 1 mile = 5280 ft 1 mile = 1760 yd 1 mile = 63,360 in

Time 1 minute (min)=60 seconds (sec) 1 hour (hr) = 60 min 1 hr = 3600 sec 1 day = 24 hours 1week = 7 days 1 year = 365 days

Liquid Measure 1 gallon (gal) = 4 quarts (qt) 1 qt = 2 pints (pt) 1 pt = 2 cups (c) 1 c = 8 fluid ounces (fl oz) 1 gal = 128 fl oz

Weight 1 pound (lb) = 16 ounces (oz) 1 ton = 2000 lb

Metric Weights and Measures Units smaller than a meter have LATIN prefixes Deci-means 10 (10decimeters in 1 meter) Centi –means 100 (100 centimeters in 1 meter) Milli-means 1,000 (1,000 millimeters in 1 meter)

Metric Weights and Measures Units larger than a meter have GREEK prefixes Deka-means 10 (10 meters) Hecto-means 100 (100 meters) Kilo –means 1,000 (1000 meters)

Metric Weights and Measures Kilometer (1000 m) Hectometer (100 m) Dekameter (10 m) METER (1m) Decimeter (0.1 m) Centimeter (0.01 m) Millimeter (0.001)

Practice Look at your stair steps and remember every step is a power of ten (its all about the zeros) 1.How many centimeters in a kilometer? 2.How many millimeters in a dekameter? 3.How many deciliters in a kiloliter? 4.How many grams in a kilogram?

More Metric Liters measure capacity (liquids) Grams measure mass (solids) Meters measure distance

Day Two Practice: 30 miles in one hour is how many feet in one hour? 15 feet in 1 sec is how many in inches in 1 second? 6 yards in 2 seconds is how many feet in one second?

Practice: 22 cups per minute is how many pints per hour? 250 miles per year is how many feet per day? 30 feet per second is how many miles per hour?

Practice: 1500 ounces per second is how many gallons per minute? 10 gallons per hour is how many pints per minute? 4 miles per hour is how many feet per second?
