Which unit categories are supported?
This tool supports Length, Weight, Temperature, Volume, Speed, and Area — covering the most common conversion needs for everyday and technical use.
How accurate are the conversions?
Conversions use standard internationally accepted factors. Results are shown to up to 8 significant figures, which is sufficient for most practical purposes.
Why is temperature conversion different from other units?
Temperature scales like Celsius, Fahrenheit, and Kelvin use offset formulas rather than simple multiplication factors, so they require separate conversion logic.
Which unit categories does this converter support?
Length (metres, kilometres, miles, feet, inches), weight (kilograms, pounds, ounces, grams), temperature (Celsius, Fahrenheit, Kelvin), volume (litres, gallons, millilitres, fluid ounces), speed (km/h, mph, m/s), and area (square metres, square feet, acres, hectares).
How do I convert kilometres to miles?
Select the Length category, set the input unit to Kilometres and the output unit to Miles, then enter the value. One kilometre equals approximately 0.621371 miles. The same approach works for any supported unit pair.
