Temperature

The temperature scales measure the heat present in a substance or object.

Some interesting temperature facts

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.

Freezing points

If you raise the temperature of a substance above its freezing point, it will become a liquid. The pouring temperature will be slightly higher.

  • Liquids
    • Water = 0
    • Salt water (35 salinity) = -2
  • Waxes
    • Soy Container Wax = 46
    • Palm wax = 58
    • Parfin wax = 54
    • Soy Pillar Wax = 61
    • Beeswax = 62
  • Metals
    • Tin = 231
    • Cadmium = 321
    • Lead = 327
    • Zinc = 419
    • Antimony = 630
    • Aluminium = 660
    • Sliver = 961
    • Gold = 1064
    • Copper = 1084
    • Palladium = 1554
    • Platinum = 1772

Imperial volumes

  • 8 fluid drachms = 1 fluid ounce
  • 5 fluid ounce = 1 gill
  • 20 fluid ounce = 1 pint
  • 2 pints = 1 quart
  • 8 pints = 1 gallon
  • 2 gallons = 1 peck
  • 4 pecks = 1 bushel

See the coopering guide for cask capacities

Volume calculator

To work out the amount of liquid that can fit in a rectangular container, simple add the height, width and depth in inches to the form below. The result is rounded up if above .5:

Area

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.

Imperial Areas

  • 144 inches = 1 square foot
  • 9 square feet = 1 square yard
  • 484 square yards = 1 square chain
  • 100 square chains = 1 square furlong
  • 4,840 square yards = 1 Acre
  • 640 acres = 1 square mile
  • 64 square furlong = 1 square mile

Metric Areas

  • 10,000 centimetres = 1 square metre
  • 10,000 square metres = 1 square hectare

Weight

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.

Imperial Weight Abbreviations:

  • Grain = gr
  • Drachm = drc

  • 2240 pounds = 1 ton
  • 2 stones = 1 quarter
  • 4 quarters = 1 hundredweight
  • 20 hundredweight = 1 ton

Length

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.
