result = value × conversion_factorvalueInput value in the source unitconversion_factorFactor to convert from source to target unitUnit conversion works by multiplying the input value by a conversion factor. For temperature, offset equations are used instead. All conversions are performed via a base unit (meters for length, kilograms for weight, etc.).
Unit conversion is a fundamental skill needed in science, engineering, cooking, travel, and everyday life. Whether converting miles to kilometers for a road trip, pounds to kilograms for a recipe, or Celsius to Fahrenheit for weather, having a reliable unit converter saves time and prevents costly errors.
Select your category, choose the source unit and target unit, enter the value, and the converter instantly calculates the result with the conversion formula. All conversions use internationally standardized factors.
This converter covers six categories — length, weight, temperature, volume, area, and speed — handling the most common real-world conversion needs. The formula display helps you learn the conversion factors for future reference.
Ensure you select units from the same category (e.g., don't mix length and weight). For temperature, remember that Celsius and Fahrenheit use offset formulas, not simple multiplication. Always double-check results for critical applications.
Convert between major world currencies using reference exchange rates. Supports USD, EUR, GBP, INR, JPY, CAD, AUD, and 15+ currencies.
