How to Use This Calculator

Enter your Value (e.g. 1), From — choose from , , , and To — choose from , , . Results update instantly as you type — adjust any value to compare scenarios.

The Formula

Unit conversion uses a fixed conversion factor between the two units. Multiply the input value by the factor to get the result. For temperature, the formula depends on the scales (e.g., °C to °F: multiply by 9/5 and add 32).

Worked Example

The weather forecast says it is 35°C outside. You want to know what that is in Fahrenheit. Using the formula °F = + 32, 35°C converts to 95°F. This converter handles Celsius, Fahrenheit, and Kelvin instantly.

Understanding Your Result

Weight and mass conversions: 1 kg = 2.2046 lbs; 1 stone = 14 lbs = 6.35 kg; 1 metric ton = 1,000 kg = 2,204.6 lbs. For shipping and freight: dimensional weight (DIM weight) often applies — carriers charge for whichever is higher between actual weight and volumetric weight (L × W × H ÷ 139 for inches, or ÷ 5,000 for cm in kg). Always confirm whether the target application needs mass (kg) or weight-force (Newtons) — they differ by the local gravitational constant.
