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.
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.
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."
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.
An ounce (oz) is a unit of mass in the imperial system, equal to 0.0625 (or 1/16) Pounds (lb).
While most people are familiar with the standard ounce used for groceries, there is another crucial measurement called the Troy Ounce.
The standard ounce, officially known as the Avoirdupois ounce, is approximately 28.35 grams and is used for weighing everyday items.
The Troy ounce, however, is slightly heavier, at approximately 31.1 grams, and is the universal standard for measuring precious metals, such as gold, silver, and platinum. This distinction is vital in the jewelry and investment markets.
A common point of confusion is the difference between an ounce (oz) and a fluid ounce (fl oz).
An ounce is a unit of mass (weight), while a fluid ounce is a unit of volume.
For example, you would use ounces to weigh a block of cheese but fluid ounces to measure a glass of milk. The weight of one fluid ounce of a liquid depends entirely on its density; one fluid ounce of honey, for instance, weighs more than one fluid ounce of water.
The word "ounce" comes from the Latin uncia.
In ancient Rome, an uncia was one-twelfth of a libra (the Roman pound), and that system helped shape many European measures.
Today's avoirdupois ounce is one-sixteenth of a pound. However, the name still preserves a direct link to Rome's old system of weights and measures.
