How to use Unit Converter

  1. Choose the category

    Length, weight, volume, area, speed, temperature and so on.

  2. Pick the units

    Select what you are converting from and to.

  3. Enter the value

    The result updates as you type.

  4. Check the variant

    For volume and weight, confirm whether you need US or imperial — they differ.

When to use Unit Converter

  • Converting a recipe written in different units
  • Checking a height or weight given in unfamiliar units
  • Converting measurements for a DIY or construction project
  • Understanding product specifications listed in another system

FAQ

Length, weight, volume, area, temperature, speed, time, and data (bytes). Each category includes a wide range of metric and imperial units.
Conversions use precise mathematical factors and are accurate to the limits of floating-point arithmetic. Temperature uses exact formulas.
No. All conversions run entirely in your browser. Nothing is sent to a server.
Rounding, and unit definitions. Some units have more than one standard — a US gallon and an imperial gallon differ by about 20% — so check which variant a tool is using for volume and weight.
Mass is how much matter something contains, measured in kilograms or pounds. Weight is the force gravity exerts on it, properly measured in newtons. Everyday usage treats them as the same because gravity is effectively constant on Earth.
Yes. Conversion is arithmetic against fixed ratios with no lookup required, so it works with no connection.
Weight, considerably. A cup of flour can vary by 20% depending on how it was packed, whereas 120 grams is 120 grams. Serious baking recipes give weights for exactly this reason.

About Unit Converter

Unit conversion is straightforward arithmetic with fixed ratios, which is exactly why it works offline and instantly. The difficulty is never the maths — it is picking the right unit.

Several everyday units have more than one definition, and the difference is large enough to matter. A US gallon is 3.785 litres while an imperial gallon is 4.546 — a 20% gap. US and UK fluid ounces, pints and tons all differ too. A recipe or specification that just says "gallon" is ambiguous, and you need to know its origin.

The other frequent confusion is mass versus weight. Kilograms and pounds measure mass; newtons measure force. In everyday use the distinction is ignored because gravity is effectively constant, but it matters in physics and engineering contexts where the two are genuinely different quantities.

Tips and limits

  • US gallon 3.785 L, imperial gallon 4.546 L — a 20% difference.
  • US and UK fluid ounces, pints and tons all differ. Check the source.
  • Kilograms and pounds are mass; newtons are force. Not interchangeable in technical work.
  • Conversion is fixed-ratio arithmetic, so it works offline with no lookup.
  • For cooking, weight is far more reliable than volume — especially for flour.
