Although you must use metric measurements in the England, Scotland or Wales (grams, kilograms, millilitres or litres), it is the law when selling package and loose goods, many people think in the older imperial system (ounces, pounds, inches and pints). Northern Ireland is different. The good news is that you can still buy milk, beer and cider in pints and if you deal in precious metals you can use troy ounces. If you want to include the imperial measurement on your packaging you can do but it needs to be less noticeable than the metric.
On this page you can convert all sorts on measurements from metric to imperial and back again. Enter the amount in the highlighted box and the click on the = sign to convert.
The temperature scales measure the heat present in a substance or object.
If you raise the temperature of a substance above its freezing point, it will become a liquid. The pouring temperature will be slightly higher.
A three-dimensional measure of the space inside a container or the amount of a substance.

To work out the amount of liquid that can fit in a rectangular container, simply add the height, width and depth in inches to the form below. The result is in gallons and rounded up if above .5:
The measure of an area is two dimensional, like a measure of land or the floor space at a fair. The surface area of a standard craft table of 6ft by 2ft 6 inches = 15 square feet.
How heavy an object or substance is, depends on its relative density. Lead and gold are dense and are therefore heavy, wax and wood are less dense and therefore not as heavy.
It would be a shame to lose imperial lengths, as they are more human than metric. They are based on the size of part of the body like, hands, feet, palms which can be used whilst crafting.
