What is Unit Converter?
Convert between length, weight, volume, temperature, speed, and area units — with more than 30 units supported across the SI and US systems. Live input: type in any field and the others update immediately. Great for recipes, fitness logs, construction specs, and cross-border shopping where two systems always disagree.
How do I use Unit Converter?
- Pick a category: length, weight, volume, temperature, etc.
- Type a value in any unit; all other units update live.
- Copy the value you need.
When should I use Unit Converter?
Unit Converter is for physical units. For number-base conversions (binary/decimal/hex/octal), use Binary ↔ Decimal or Base Convert. For currency (fluctuates daily), use Currency Converter.
Which unit categories are supported?
Length, weight, temperature, volume, area, speed, time, energy, pressure, and digital storage. Pick a category, pick source and target units — the conversion updates live.
Are the conversion factors accurate?
Yes — sourced from NIST and ISO reference tables. Temperature uses exact formulas (not approximations); distance uses the official metre / foot definitions.
Can I convert scientific units?
Yes. Energy supports joules, calories, BTU, electronvolts; pressure supports Pa, bar, psi, atmospheres; storage supports SI (MB) and binary (MiB) variants separately.
