Metric & Imperial Unit Conversion Factors

Standard international conversion ratios and algebraic formulas across physical measurement domains.

Measurement Dimension From Unit To Unit Exact Multiplier / Formula
Length Meter (m) Feet (ft) 1 m = 3.28084 ft
Length Kilometer (km) Mile (mi) 1 km = 0.621371 mi
Weight / Mass Kilogram (kg) Pound (lb) 1 kg = 2.20462 lb
Weight / Mass Gram (g) Ounce (oz) 1 g = 0.035274 oz
Temperature Celsius (°C) Fahrenheit (°F) °F = (°C × 9/5) + 32
Temperature Celsius (°C) Kelvin (K) K = °C + 273.15

Frequently Asked Questions

Our conversions use precise, standardized mathematical constants. However, outputs are rounded to a maximum of 6 decimal places for readability.

Unlike length or weight, temperature scales do not start at a common zero point (except Kelvin). We use the exact algebraic formulas to convert between Celsius, Fahrenheit, and Kelvin, ensuring absolute accuracy.

To keep the interface clean, we group units by their physical property. You can only convert Length to Length, Weight to Weight, and Temperature to Temperature.
