Understanding Weight and Mass Conversions

Weight and mass are fundamental measurements used daily, from cooking recipes to calculating shipping costs. While technically distinct (mass is the amount of matter, weight is the force of gravity on that mass), the terms are often used interchangeably in everyday contexts. Different systems are used globally, primarily the Metric System (using kilograms, grams) and the Imperial/US Customary System (using pounds, ounces, stones).

This converter helps you easily switch between these units. Whether you're following a recipe, managing inventory, or working on a science project, accurate weight conversion is essential.

Common Weight/Mass Units

  • Kilogram (kg): The base unit of mass in the Metric system.
  • Gram (g): 1/1000th of a kilogram. Commonly used for smaller measurements.
  • Pound (lb): A standard unit of weight in the Imperial/US systems.
  • Ounce (oz): 1/16th of a pound. Used for smaller weights.
  • Stone (st): An Imperial unit equal to 14 pounds, often used for body weight in the UK and Ireland.
  • Tonne (t) / Metric Ton: 1000 kilograms.
  • US Ton (short ton): 2000 pounds.

Frequently Asked Questions about Weight & Mass

How many pounds are in a kilogram?

There are approximately 2.20462 pounds in 1 kilogram. To convert kg to lbs, multiply by 2.20462.

What is the difference between an ounce and a fluid ounce?

How many grams are in an ounce?

There are approximately 28.3495 grams in 1 ounce. To convert ounces to grams, multiply by 28.3495.

How do I convert pounds to kilograms?

To convert pounds to kilograms, multiply the number of pounds by 0.453592. For example, 10 pounds equals approximately 4.53592 kilograms.

How many pounds are in a stone?

There are exactly 14 pounds (lbs) in 1 stone (st).
