Stone Meaning
The word "stone weight" is taken from the use of stones for weights, a practice that dates back into the stone measurement.
So, What is The Definition of Weight?
Weight is the relative mass of the body. It is also known as the amount of matter a body contains. Weight is also called the force of gravity, which acts in the downward direction.
When the lift moves upward, its product of mass and acceleration goes upward; however, the weight acts downward.
In this article, we will understand the smallest unit of weight, a stone definition in detail.
Stone Definition
A stone or stone unit of weight, the stone symbol is st. It is an English and imperial unit of mass that is equal to 14 pounds or approximately 6.35 kg. The stone continues in traditional use in the United Kingdom and Ireland for measuring body weight.

Irrespective of the purpose of the rock, each stone has a specific purpose and a history that stretches beyond the time limit. Some of them reside outside the universe and some have been home for millions of years.
The energy these stones bear has something to do with inner energy. This is the reason many cultures use their family stone symbol to meditate or pray. Also, some have faith that stones have spiritual powers.

So, do you know what unit weight is?
If we go with the order of weight, the smallest unit of weight is an ounce, then greater is pound and ton is the largest unit of weight. Stone weight is 6.35 kg, which we call 1 stone in kg.
History of Stone
A stone has been traditionally used for weight measurement in the United Kingdom & Ireland.
Other countries like England and other Germanic-speaking countries of northern Europe formerly used numerous standardized "stones" for trading purposes, with their values ranging from 5 to 40 local pounds (approximately 3 to 15 kg) depending on the geographic location and objects weighed. However, With the arrival of metrication in the mid-19th century, Europe's various "stones" were replaced by or adapted to the kilogram.
During ancient times, a Biblical law was against the carrying of "diverse weights, a large and a small. The law carried a statement that "no one shall carry a stone and a stone, neither a large nor a small".
In the Jewish world, there was no standardized "stone"; however, in Roman times, stone weights were created to multiples of the Roman pound. Such weights constantly changed in quality, like, the Yale Medical Library held between 10 to50-pounds and these were stated examples of polished serpentine, while a 40-pound was an example at the Eschborn Museum made of sandstone.
Stone Unit of Weight
Below is the chart that shows the value of a stone unit of weight with various units:
Metric Stone
In the city of the Netherlands, the metric system was adopted in 1817, the pond a.k.a pound was set equivalent to a kilogram, and the steen a.k.a stone was previously been 8 Amsterdam pond, i.e., 3.953 kg, and was redefined as 3 kg.
Ordinarily, during the modern period in Dutch, a pound was used as an alternative to 500 grams/half a kg, while the ounces was used for a weight of 100 gms, being equal to 0.2 pounds.
FAQs on Stone Unit of Weight
1. What is a 'stone' as a unit of weight?
A 'stone' (often abbreviated as 'st') is an imperial unit of mass that is commonly used in the United Kingdom and Ireland to measure body weight. Although the kilogram is the official unit, the stone remains popular in everyday, non-scientific use. One stone is officially defined as being equal to 14 pounds.
2. How many kilograms and pounds are in one stone?
The conversion for one stone is straightforward and important to know for comparing weights. Here are the key equivalents:
- 1 stone = 14 pounds (lbs)
- 1 stone = approximately 6.35 kilograms (kg)
3. How can you convert a weight from kilograms (kg) to stones?
To convert your weight from kilograms to stones, you can use a simple calculation. Since one stone is about 6.35 kg, you just need to divide your weight in kilograms by 6.35. For example, a person weighing 63.5 kg would be exactly 10 stone (63.5 ÷ 6.35 = 10).
4. Is 'stone' a unit of mass or weight? What is the actual difference?
This is a common point of confusion in physics. In everyday language, we use 'stone' to describe mass, which is the amount of matter in an object. However, in strict scientific terms, weight is the force of gravity acting on that mass. While you might say you 'weigh' 11 stone, you are actually stating your mass. Your weight, a force measured in Newtons, would be different on the Moon, but your mass in stones or kg would remain the same.
5. Why is the 'stone' unit still used for measuring body weight, especially in the UK?
The use of the stone is largely historical and cultural. It originated centuries ago as a measure for agricultural goods. Over time, it became the conventional unit for measuring a person's weight in the UK and Ireland. Despite the official adoption of the metric system (kilograms), the stone persists in casual, everyday contexts because it is familiar and deeply ingrained in the culture.
6. If stones are used for weight, why don't scientists use them in calculations?
Scientists around the world rely on a standardised system to ensure their work is consistent, accurate, and can be easily understood by others. This system is the International System of Units (SI). For mass, the SI unit is the kilogram (kg), and for force (like weight), it is the Newton (N). Using a single, universal standard prevents confusion and errors that could arise from using regional or historical units like the stone.
7. What are some real-world examples of things measured in stones?
The most common application of the stone unit today is for measuring human body weight. Beyond that, its use is quite limited. Historically, it was used to weigh agricultural products like wool. For a modern comparison, an average-sized domestic cat weighs about half a stone, while a 10-year-old child might weigh around 5 to 6 stone.
