Weight vs Mass: What's the difference?
Technically, mass is the amount of matter in an object (measured in kilograms), while weight is the force exerted by gravity on that mass (measured in newtons). However, in everyday usage, "weight" commonly refers to mass, and this converter handles both concepts using standard mass units.
Common weight/mass relationships
- 1 kilogram = 1,000 grams
- 1 pound ≈ 0.453592 kilograms
- 1 ounce ≈ 28.3495 grams
- 1 metric ton = 1,000 kilograms
When to use each weight unit
Kilograms and grams are the standard units in most countries and in scientific contexts. Pounds and ounces are primarily used in the United States and a few other countries. Metric tons (tonnes) are used for very large masses, while milligrams are used for very small masses in pharmaceutical and laboratory settings.
Frequently Asked Questions
- How many pounds are in a kilogram?
- One kilogram equals approximately 2.20462 pounds. This is one of the most commonly used weight conversions.
- Is mass the same as weight?
- Mass is the amount of matter in an object and doesn't change with location. Weight is the force of gravity on that mass and varies with gravitational field strength. In everyday usage, the terms are often used interchangeably.
