From Grams to Pounds: A Guide to Units of Weight ⚖️
Weight, or more accurately mass, is a fundamental property of matter. Like length, the world is divided between two primary systems of measurement: the Metric system (used by most of the world) and the Imperial system (used primarily in the United States). This tool provides a seamless way to convert between them.
The Metric System of Mass
The Metric system is built on a logical, base-10 structure, making it easy to understand and convert within the system. The base unit of mass is the kilogram (kg).
- 1 Tonne (t) = 1,000 kilograms
- 1 Kilogram (kg) = 1,000 grams
- 1 Gram (g) = 1,000 milligrams (mg)
This system is the standard for science, international trade, and daily use in most countries.
The Imperial and U.S. Customary Systems of Weight
The Imperial system uses units with more varied and historical relationships. The most common units are the pound and the ounce.
- 1 Ton (US) = 2,000 pounds
- 1 Stone (st) = 14 pounds (commonly used in the UK)
- 1 Pound (lb) = 16 ounces (oz)
