Understanding Stones and Pounds
What is a Stone?
The stone is a traditional British unit of weight used primarily for measuring body weight. One stone is equal to 14 pounds or approximately 6.35 kilograms. While it has largely been replaced by metric units in most contexts, it remains commonly used in the United Kingdom and Ireland for expressing human body weight.

The stone unit dates back to medieval times when merchants used stone weights to measure goods in markets. The weight of a stone varied depending on the commodity being measured, but the 14-pound stone became standardized for most purposes, particularly for measuring wool and later human body weight.

Frequently Asked Questions
How many pounds are in a stone?
There are exactly 14 pounds in one stone. This conversion factor has been standardized and is consistent across all uses of the stone as a unit of weight measurement. For example, if someone weighs 10 stones, that equals 140 pounds (10 × 14 = 140).
Why do British people use stones for weight?
The stone is a traditional British unit that has been used for centuries, particularly for measuring body weight. It provides a convenient middle ground between pounds and hundreds of pounds, making it easier to express adult body weights with smaller numbers. For example, saying "12 stone" is more concise than "168 pounds." Cultural tradition keeps this unit in common use, especially in the UK and Ireland, despite the global shift toward metric measurements.
How do you convert stones and pounds to just pounds?
To convert a weight expressed in stones and pounds (e.g., 12 st 8 lbs) to pounds only, multiply the stone value by 14 and add the remaining pounds. Using the example:
- 12 stones × 14 = 168 pounds
- 168 pounds + 8 pounds = 176 pounds total
Is the stone used anywhere besides the UK?
The stone is primarily used in the United Kingdom and Ireland for measuring human body weight. While it was historically used in other Commonwealth countries, most have transitioned to metric units (kilograms). The United States never adopted the stone, preferring pounds as the standard imperial weight unit. Today, the stone remains most commonly used in British and Irish contexts, particularly in healthcare, fitness, and everyday conversation about body weight.
What is 168 pounds in stone?
168 pounds equals exactly 12 stones. To calculate this, divide 168 by 14 (since 1 stone = 14 pounds): 168 ÷ 14 = 12 stones. This is a commonly referenced weight as it represents a typical adult weight in the UK weight measurement system.
Should I use stones or kilograms for weight?
The choice depends on your location and context. If you're in the UK or Ireland and discussing weight in everyday conversation, stones are commonly understood and accepted. For medical records, scientific work, or international contexts, kilograms are generally preferred as they're part of the standardized metric system. Many modern scales display both units, allowing you to choose based on your preference and audience.
