Converting Units

when we convert units, we are taking one unit and making an equivalent value into another unit.

Example: m into kilometers, or lbs into tons

When Converting units we follow this rule

BIG --- small = MULTIPLY

3 yd-- ft? we 3 x 3 = 9ft because 1 yd=3ft so 3 yd x 3ft each = 9ft

small---BIG = DIVIDE

6 c -- pints ? we are doing small units to big

6c /2 because 1pint=2cups so if I have 6c/2 = 3 pints
