Measurement is as old as history. There are 3 systems of measurement: the English, the Metric and the System International D'unites (or SI). When America separated from England, the colonies retained the English system - at about the same time the metric system was developed in France. This metric system was later modified to develop the SI system. Here we have some conversion calculators for weight, volume, length and pressure.
This is how these work: just type a number in the field you know, and press the calculate button. It will convert the units for the rest of the boxes. Note that the units are converted first to the first box of each table, and then converted to the respective unit. This double conversion is why if you put in 1 gal, you will not get exactly 8 pints.

|A pound is a unit of force and a kilogram is a unit of mass. This conversion implies that 1 lb of weight (which is a force) equals the weight exerted by 0.4536 kg of mass assuming the gravity is 9.8m/s2. On the moon, a kilogram will weigh less but still have the same mass.|
