Weight Converter

Formula • Worked example • Interpretation

Convert mass measurements

Translate between kilograms, grams, pounds and other supported mass units for recipes, shopping and everyday measurements.

Calculation method

What your result means

Display rounding may shorten a converted measurement; retain full precision for repeated conversions or calculations.

Tips for better calculations

If a label provides both metric and imperial quantities, treat them as rounded packaging values rather than exact mathematical equivalents.

Assumptions and limitations

“Weight” commonly refers to mass in everyday use, but scientific weight is a force. Regional ounces and specialty units may not match the standard definitions used here.
