What's the difference between mass and weight?
Mass is a measure of the amount of matter in an object, while weight is the force of gravity on that mass. On Earth, these are often used interchangeably for practical purposes.
How accurate are the conversions?
The conversions are mathematically precise to six decimal places, which is more than sufficient for most practical applications. The calculations use standard conversion factors recognized internationally.
Why are there different types of tons?
Different regions historically developed different standards. The metric ton (1000 kg) is used internationally, while the short ton is common in the US, and the long ton was traditionally used in the UK.
