This page is all about converting from one unit of measurement to another. Usually this is for either converting from or to metric and imperial measurements.
Enter the amount in the highlighted box and the click on the = sign to convert.
Sound moves slower at lower temperatures and faster at higher temperatures. At -25°C sounds moved at just 315 metres per second but at +35°C sounds moves at 351 metres per second.
Temperatures are not only measured in centigrade and fahrenheit. There are also the scales of Kelvin, Rankine, Delisle, Newton, Reaumur and Rømer.
0 K (Kelvin) is absolute zero, (not something you want to be around to measure). The scale was created by Belfast born, Lord Kelvin.
The fahrenheit scale was first proposed back in 1724 by Daniel Gabriel Fahrenheit. It is not commonly used in the UK any more but it is still used in the United States.
Although a lot of people in the UK still use the term centigrade, as we have here, back in 1948 (because of international confusion) it was agreed that we would all use Celsius. The scale was firstly created by Andres Celsius back in 1742, although in reverse.
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.

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.
It would be a shame to loose 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.
