Unit Converter

Rates & guidance reviewed

Switching between metric and imperial units is a daily need — recipes, DIY, travel and science homework. This free unit converter covers length, weight, temperature and volume with clear, accurate conversions.

Pick a category, choose from and to units, and enter a value. Results update as you type. Ideal for UK users who work with mixed unit systems.

Conversions use standard factors (e.g. inch = 25.4 mm exactly). Temperature uses the standard °C/°F/K formulae.

Metric and imperial in everyday UK life

The UK officially uses metric for most purposes, but miles, pints, feet and stones still appear in road signs, pubs and body weight. A reliable converter helps with DIY measurements, recipes and travel.

Temperature conversion is not a simple multiply: °C to °F uses ×9/5 then +32. Length and mass use fixed factors (an inch is exactly 25.4 mm). Results are rounded for readability.

Frequently asked questions

Which unit systems are supported?
Common metric and imperial units for length, mass/weight, volume, plus Celsius, Fahrenheit and Kelvin for temperature.
How accurate are the conversions?
They use standard international conversion factors. Display is rounded for readability; underlying maths uses full floating-point precision.
Is weight the same as mass here?
For everyday conversion (kg, lb, st) we treat them as mass-equivalent units as commonly used on kitchen and bathroom scales.
Can I convert between any two units in a category?
Yes. Pick any from/to pair within the same category.
