One **stone** is 14 pounds.

Half a stone is called a **clove**, which is 7 pounds.

It works really neatly to say that any character can carry as may cloves as his strength, unencumbered. I.e., a character with 13 strength can carry 13 cloves unencumbered.

Leather armour is equivalent to 2 cloves, chainmail 4 cloves, and plate armour 6 cloves.

Pretty much any other item that is worth worrying about is close enough to 1 clove. I.e., swords, axes, shields, helms, bow & arrows, lantern & oil, a week’s rations, etc. are all equivalent to 1 clove in terms of mass, bulk and overall encumbrance. A sack of 100 coins is also 1 clove. You might call two-handed swords and full-sized shields 2 cloves.

There is also another measure called a **hundredweight**. A hundredweight is 8 stone (or 112 pounds, which I guess must have been near enough to 100 pounds in medieval math).

A hundredweight was the maximum load an ordinary labourer could be expected to bear day in, day out. Which tells us that 8 stone (16 cloves) is the maximum encumbered load an ordinary man could carry. Let’s say our "ordinary man" might have 8 to 13 strength, then men with 8 strength could carry up to 8 cloves unencumbered, and up to 16 cloves encumbered.

Finally, a **ton** is 20 hundredweights. This is equivalent to 160 stone, or 320 cloves, or 32,000 coins. This tells us that we would need a work crew of 20 men to haul away a dragon’s hoard of 32,000 coppers.

A horse, by the way, could typically haul the equivalent of what 6 ordinary men could haul.
