Ton to Stone Conversion Formula

To convert from Ton (t) to Stone (st), use the following formula:

 Stone (st)\textbf{ Stone} \text{ (st)}

=2000×114× Ton (t)= 2000 \times \frac{1}{14}\times \textbf{ Ton} \text{ (t)}

=142.85714285714285714× Ton (t)= 142.85714285714285714\times \textbf{ Ton} \text{ (t)}

Example

Let's convert 5 Ton (t) to Stone (st).

Using the formula:

5×142.85714285714285714=714.28571428571428575 \times 142.85714285714285714 = 714.2857142857142857

Therefore, 5 Ton (t) is equal to 714.2857142857142857714.2857142857142857 Stone (st).

What is a Ton (t)?

A ton (t) is a standard unit of mass.

In the United States, a ton is equivalent to 2,000 pounds (lb).

That said, the exact amount can vary depending on the system you use—US, British (Imperial), or metric—so it's essential to know which "ton" you mean to avoid mistakes.

How Many Pounds Are in a Ton? Short vs. Long vs. Metric

While the US short ton is widely used, it's not the only definition.

The three main types of tons have different weights:

  • Short Ton (US): This is the standard ton in the United States. It equals 2,000 pounds.
  • Long Ton (UK): Also known as the imperial ton, this is used in the United Kingdom. It equals 2,240 pounds.
  • Metric Ton (Tonne): Used globally in the metric system, a tonne is defined as 1,000 kilograms. This is equal to approximately 2,204.6 pounds.

The distinction between these units is crucial in international shipping and trade to avoid costly confusion.

Ton vs. Tonne: Why Spelling Matters

The spelling of the word tells you exactly which measurement system is being used.

  • "Ton" refers to the imperial units—either the short ton (2,000 lbs) or the long ton (2,240 lbs).
  • "Tonne" (spelled with an "ne") specifically refers to the metric unit of 1,000 kilograms.

Using "tonne" ensures precision and is the standard unit of measurement for science and international commerce.

The Surprising Origin of the Ton Measurement

The word "ton" originates from the Old English "tunne," which was a large cask used for storing wine, also known as a tun.

These casks were so typical that the weight of a full one became a standard unit of measurement.

Over time, this was standardized to 2,000 pounds, becoming the ton we use in the United States today.

What is a Stone (st)?

The stone (st) is a unit of measurement equal to 14 pounds (lb).

It's part of the imperial system and is still commonly used in a few countries, especially for weighing people.

How Many Kilograms are in a Stone?

For use in international contexts or scientific applications, the stone is often converted to the metric system.

One stone is equal to exactly 6.35029318 kilograms (kg).

This precise conversion is used in international trade and science to ensure everyone is using the exact standard measurement.

Why is Body Weight Measured in Stone?

Although it's an older unit, the stone remains the primary unit of measurement for body weight in the United Kingdom and Ireland.

It's common to hear someone state their weight as a combination of stone and pounds, like "12 stone 6 pounds."

Where Did the Stone Unit Come From?

The stone traces its origins back to the medieval English wool trade, where a "stone of wool" referred to a standard 14-pound measure used for buying and selling.

Stones for other goods could vary in weight—for example, a stone of glass was just 5 pounds—but over time, the 14-pound stone became the official legal standard.

What is the imperial system?

The imperial system is a system of measurement that was first defined in the British Weights and Measures Act of 1824. It's known for using units like inches, feet, pounds, and gallons. While most of the world now uses the metric system, the imperial system remains the official system of measurement in the United States and is still used in specific contexts in other countries, such as the United Kingdom and Canada.
