1. Objective
The learner will determine appropriate measuring tools, units, and scales

2. The Metric System Length = Meters Capacity = Liters Weight = Grams

3. The Customary System Length Capacity 8 fluid ounces (oz) = 1 cup (c)
12 inches (in) = 1 foot (ft)
3 ft = 1 yard (yd)
5,280 ft = 1 mile (mi)
Capacity
8 fluid ounces (oz) = 1 cup (c)
2 c = 1 pint (pt)
2 pt = 1 quart (qt)
4 qt = 1 gallon (gal)
Weight
16 dry ounces (oz) = 1 pound (lb)
2,000 lb = 1 ton (T)
