Imperial units are measurements used in the United States, as opposed to the metric system used in all other countries except Burma and Liberia. The metric system is a system of weights and measurements based on the decimal system where units are expressed in groups of ten. Imperial units include the yard (3 feet, or 0.9144 meters) the foot (12 inches, or 304.8 millimetres), the ounce (1⁄7.26 Kilogram, or 28.349523125 grams), and the ton (1016 Kilogram, or 1,016.0469088 kilograms). Converting Imperial fractions into metric amounts can be done manually or with online calculators.

## Instructions

1. 1

Measure the amount, weight or length of the item in the Imperial system. Convert the fraction of the measurement to a decimal place. To do this, divide the top number of the fraction by the bottom number. If your Imperial measurement is 6 7/8 inches, divide the 7 by 8 to get .875. The number is then 6.875.

2. 2

Consult a metric conversion chart for the exact conversion formula you need. The formula is different for weights, lengths and fluid amounts. To continue the example above, if you have 203ml of liquid, you would multiply that amount by 28.413ml to get total litres; in this case, 0.20 litres. If you have 6.875 inches, you would multiply that by 2.54 centimetres to get the total length in centimetres: 17.46cm.

3. 3
