# Short Tons to Long Tons (ton to long tn)

Source: https://www.unitconvertercalculator.com/weight/short-tons-to-long-tons/

**1 ton = 0.89285714285714 long tn**

One short ton equals approximately 0.8929 long tons. The American short ton at 2,000 pounds is about 10.7 percent lighter than the British long ton at 2,240 pounds. This seemingly modest difference becomes commercially significant at scale: a 1,000-ton contract means 240,000 pounds more cargo if specified in long tons versus short tons.

## Units

### Short Ton (ton)

A short ton (US ton) is a unit of mass equal to exactly 2,000 pounds or 907.18474 kilograms. It is the standard ton used in the United States for commerce, industry, and shipping.

### 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

Shipping contracts, naval displacement figures, and mining production statistics all require careful distinction between short and long tons. Historical documents from the 19th and early 20th centuries may use either without explicit specification, requiring contextual analysis to determine which ton is intended.

## Good to Know

The short-ton-to-long-ton conversion captures the moment when America and Britain diverged in their approach to the same measurement concept. Both countries wanted a 'ton' near 2,000 pounds, but Britain rounded up to 2,240 (preserving the 112-pound hundredweight tradition) while America rounded down to 2,000 (embracing decimal simplicity). The 10.7 percent gap between them has been a source of commercial confusion ever since.

## FAQ

### How many long tons are in one short ton?

One short ton equals approximately 0.8929 long tons, or equivalently, one long ton equals about 1.12 short tons. The long ton is 12 percent heavier.

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

Multiply short tons by 0.8929 (or divide by 1.12). For example, 100 short tons equals about 89.29 long tons.

### Why are there two different English tons?

The British long ton (2,240 lbs = 20 long hundredweights of 112 lbs) preserved medieval trading ratios. The American short ton (2,000 lbs = 20 short hundredweights of 100 lbs) simplified the math. Neither country adopted the other's version.

## Non-Frequently Asked Questions

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

The Titanic's displacement converts to about 51,888 short tons. The 5,560-ton difference between long and short ton figures is enough to mislead anyone comparing Titanic's displacement with modern ships quoted in short or metric tons without noting the unit difference.

### Which ton is the 'real' ton?

All three tons (short, long, and metric) are equally real and legally defined. The short ton is standard in America, the long ton persists in British shipping tradition, and the metric ton dominates international trade. Calling any one of them the 'real' ton in mixed company guarantees an argument.

### What happens if a contract just says 'tons' without specifying?

Litigation happens. International trade contracts now almost universally specify the ton type to prevent exactly this ambiguity. In the US, unqualified 'ton' legally means short ton. In the UK, it historically meant long ton. In international trade, it usually means metric ton. The safest approach is to always spell it out.
