**1 st = 0.00625 long tn**

One stone equals exactly 0.00625 long tons, or equivalently, exactly 160 stones make one long ton. This clean ratio reflects the British imperial system's internal coherence: 8 stones per hundredweight times 20 hundredweights per long ton gives 160 stones per long ton, all exact integers.

## Units

### Stone (st)

A British unit of mass equal to 14 pounds or approximately 6.35 kilograms. Commonly used in the UK and Ireland for body weight.

### Long Ton (long tn)

A long ton (imperial ton) is a unit of mass equal to exactly 2,240 pounds or 1,016.0469088 kilograms. It is used primarily in the United Kingdom for shipping and naval displacement.

## Background

Historical British records expressing both body weights (in stones) and cargo weights (in long tons) share this conversion. A ship's passenger manifest listing weights in stones could be totaled in long tons for displacement calculations.

## Good to Know

The 160-stone long ton completes the British imperial weight chain: 14 pounds per stone, 8 stones per hundredweight, 20 hundredweights per long ton, giving 160 x 14 = 2,240 pounds per long ton. Every link is an exact integer, creating a system of perfect internal consistency that medieval merchants could navigate entirely through mental arithmetic.

## FAQ

### How many stones are in one long ton?

Exactly 160 stones make one long ton. This is 8 stones per hundredweight times 20 hundredweights per long ton.

### How do I convert stones to long tons?

Divide stones by 160, or multiply by 0.00625. For example, 320 stones equals exactly 2 long tons.

### Why is this ratio exact?

Because the long ton is defined through the hundredweight (20 cwt = 1 long ton) and the hundredweight through the stone (8 stone = 1 cwt), giving 160 stones per long ton exactly.

## Non-Frequently Asked Questions

### How many people weigh one long ton?

At an average of about 11 stone per person, one long ton (160 stones) equals roughly 14.5 adults. This is the capacity of a large elevator or a small bus, and it is the weight at which medieval bridges started to groan.

### If the Titanic displaced 46,328 long tons, how many stones is that?

About 7,412,480 stones. If each stone represented one person at 14 pounds, the Titanic's displacement equaled the weight of roughly 7.4 million one-stone units, or about 674,000 average adults. The actual passenger and crew complement was about 2,200, meaning the ship itself outweighed its occupants by a factor of about 300.

### Is 160 stones per long ton a useful number?

It is useful for understanding scale. Knowing that a long ton is 160 stones means you can instantly calculate that a 10-ton truck carries the equivalent of roughly 1,600 stones of cargo, or about 145 average adults' worth of weight. The stone provides a human-scale reference point for tonnage that kilograms and pounds lack.
