Examples
Example
5 miles → kilometers = 8.047 km. 72°F → °C = 22.2°C.
What this tool doesn't do
- Uses exact international definitions (1 inch = 2.54 cm); display rounds to sensible decimals.
- Volume units are excluded — US and imperial gallons/fluid ounces differ, and silent mixing causes errors.
- For engineering, medical, or legal measurements, verify against a calibrated reference.
