How accurate is the conversion?
Our converter uses exact conversion factors based on international standards (NIST/ISO). Results are accurate to 10 decimal places for all supported units.
Can I convert from any unit to any other unit?
Yes! You can convert between any two units — Metric to Imperial, Imperial to Metric, or within the same system.
What is the difference between mass and weight?
Mass is the amount of matter in an object (measured in kg, g, lb, etc.). Weight is the force of gravity acting on that mass. On Earth they are numerically equal in everyday contexts, which is why the terms are often used interchangeably.
Is my data private?
Absolutely. All conversions happen entirely in your browser. No data is ever sent to our servers or stored anywhere.
