How it works
Converts between length, weight, volume, and temperature units using standard conversion factors. Supports both metric and imperial systems.
Step by step
- 01Select a category (length, weight, volume, or temperature).
- 02Enter the value you want to convert.
- 03Choose the source unit (From) and target unit (To).
- 04The result updates instantly as you type.
- 05For temperature, special formulas handle the non-linear conversions between Celsius, Fahrenheit, and Kelvin.

Frequently asked questions
How do I convert Celsius to Fahrenheit?
Use the formula: °F = (°C × 9/5) + 32. For example, 100°C = (100 × 9/5) + 32 = 212°F.
How many feet are in a meter?
There are approximately 3.28084 feet in 1 meter.
Are cooking volumes (cups, teaspoons) exact worldwide?
Cup and tablespoon definitions differ slightly between US customary, imperial, and metric systems. This tool uses common US definitions for kitchen volumes; use metric weights for baking when precision matters.
Why does temperature conversion use different formulas than length?
Celsius and Fahrenheit have different zero points and step sizes, so you cannot multiply by a single factor like you do for meters to feet. Kelvin shares Celsius-sized steps but starts at absolute zero.
Can I use this for regulated engineering or medical dosing?
For learning and everyday estimates only. Mission-critical conversions should use validated references, calibrated instruments, and procedures approved for your industry or jurisdiction.
