Why is a long hundredweight 112 pounds?

The 112-pound standard evolved from medieval English practice. It equals 8 stones of 14 pounds each. The stone of 14 pounds was the wool trade's standard, and grouping 8 stones into a hundredweight created a convenient bulk unit. The name 'hundredweight' is misleading - it reflects an older counting convention where 'a hundred' sometimes meant 112 in commercial contexts.

How does 112 pounds relate to stones and tons?

The system builds logically: 14 pounds = 1 stone, 8 stones = 1 hundredweight (112 pounds), and 20 hundredweights = 1 long ton (2,240 pounds). Each ratio was chosen for easy mental division - halving a hundredweight gives 56 pounds, halving again gives 28, and halving once more gives 14 (one stone).

When was the 112-pound hundredweight standardized?

The key statute was Edward III's decree in 1389, which fixed the hundredweight at 112 pounds specifically for the wool trade. Before this, hundredweights varied by commodity and region - some were 100 pounds, others 108 or 120. The 1389 standardization brought order to English commerce and persisted for nearly 600 years until metrication.

Non-Frequently Asked Questions About Hundredweights (UK) to Pounds

Questions nobody should ask - but someone did.

Because 'hundred' had a broader meaning in medieval English commerce. A 'long hundred' of 112 (or sometimes 120) items was common for goods counted in bulk. The word 'hundred' simply meant 'a large, standard group' rather than the precise mathematical 100. By the time people started insisting that hundred should mean 100, the name was far too established to change.
At 112 pounds (50.8 kg), a hundredweight is near the upper limit of what a strong adult can carry unaided. Victorian coal deliverymen carried hundredweight sacks up stairs regularly, but modern occupational health standards classify 50+ kg as requiring mechanical assistance. The hundredweight represents the historical boundary between human labor and the need for tools.
That is exactly what happened. When America established its own commercial standards, it simplified the hundredweight to 100 pounds (the short hundredweight), because Americans saw no reason a unit called 'hundred' should contain 112 of anything. Britain kept the medieval 112 out of tradition. The two nations got exactly the hundredweight that matched their national character.
