1. Customary and Metric Units of Measurement
Customary units of measure are the units of measure that are used only in the United States.
Customary Measurements
Units of Length.
Units of Weight.
Units of Capacity.
Units of Time.

2. The Units of Capacity Capacity:
It is the amount a container can hold. Within the customary system, the common units for measuring capacity are fluid ounces, cups, pints, quarts, and gallons.
Examples: A standard cup of coffee. A can of coke is 12 fluid ounces. A gallon of milk.

3. Fluid Ounce (fl.oz.) One fluid ounce is equal to 2 tablespoons.
1 fl oz = 2 tbsp.

4. Gallon + + +

9. Units of Length. Length :
It is a measure of the length of an object. The common units for measuring lenght in the customary system are inches, feet, yards, and miles.
Examples: A ruler is a foot. There are 12 inches in a foot. A football field is measured in yards. The distance from here to Flagstaff is measured in miles.

10. There are 12 inches in a foot.
12 in. = 1 foot.

100 cm. = 1 m

24. 1 decimeter is equal to 10 centimeters.
Decimeter (dm.)
1 decimeter is equal to 10 centimeters.
1 dm. = 10 cm.

25. Meter (m)
A metric unit of length

26. One kilometer equals 1000 meters. 1 km. = 1000 m.
Kilometer(km.)
One kilometer equals 1000 meters km. = 1000 m.

27. The Units of Time
The common units for measuring time in the customary system are seconds, minutes, hours, days, weeks, month, and years.

28. One day is equal to 24 hours . 1 day = 24 hrs

29. One hour is equal to 60 minutes.
