Unit Converter
Convert length, weight, and temperature between common metric and imperial units.
Inputs
Converted Value
16.093440
Step by step
Convert mi to the SI base unit (meters)
10.0000 mi × 1609.344 m/mi
= 16,093.440000 m
Convert meters to km
16,093.440000 m ÷ 1000 m/km
= 16.093440 km
How it works
Length and mass conversions work by expressing the value in a base SI unit (meters or kilograms) and then converting to the target unit. Temperature uses exact Celsius/Fahrenheit/Kelvin formulas. Choose two units of the same category.
Formulas
Length and mass
result = value × (SI factor for source unit) ÷ (SI factor for target unit)
- x
- Input value
- f_from
- Metres-per-unit (length) or kg-per-unit (mass) for the source unit
- f_to
- Metres-per-unit (length) or kg-per-unit (mass) for the target unit
Temperature: °F ↔ °C
°C = (°F − 32) × 5/9 °F = °C × 9/5 + 32
Temperature: K ↔ °C
K = °C + 273.15 °C = K − 273.15
Frequently Asked Questions
Can I convert miles to kilograms?
No — those measure different things (distance vs. mass). Pick two units of the same type: length with length, weight with weight, temperature with temperature.
How precise are the conversions?
They use exact internationally-defined factors (e.g. 1 inch = 0.0254 m), so results are accurate to the displayed decimal places.
