Unit converters
Convert distance, weight, temperature, data, volume and other measurements.
About unit converters
The unit converters translate between metric and imperial measurements instantly: length (km ↔ miles, cm ↔ inches), weight (kg ↔ lbs), temperature (°C ↔ °F), plus area, volume, speed and digital data (MB, GB, TB). Values are calculated in your browser as you type — nothing is uploaded, and conversions use exact standard factors.
These cover the conversions daily life keeps asking for: recipe amounts and oven temperatures, baggage weight limits, running distances, room dimensions, shipping weights, and why a "500 GB" drive shows as 465 GB in Windows (decimal vs. binary units).
Unit converters questions
Which units can I convert?
Length, weight, temperature, area, volume, speed and digital data — with all the common metric and imperial units of each type available in both directions.
How exact are the results?
Conversions use exact standard factors — for example 1 inch = 2.54 cm and 1 lb = 453.59237 g exactly — displayed at practical precision.
Why is temperature conversion different?
Celsius and Fahrenheit have different zero points, so a formula is used instead of a simple factor: °F = °C × 9/5 + 32. That is why 0 °C equals 32 °F.
Do the converters work on mobile?
Yes — they run entirely in the browser on any device, with instant results as you type.
