TEMPERATURE CONVERSIONS
A Fahrenheit degree is smaller than a Centigrade (Celsius) degree, one Fahrenheit degree being 5/9 of a Centigrade degree.
To convert Fahrenheit degrees into Centigrade, subtract 32, multiply by 5, and divide by 9.
To convert Centigrade into Fahrenheit, multiply by 9, divide by 5 and add 32.

640 acres = 1 sq. mile |
| 365 days = 1 year (366 days in 1 leap yr.) |
43,560 sq. feet = 1 acre |
| LIQUID MEASURE |
DRY MEASURE |
| 16 ounces = 1 pint |
