Which units are supported?
Length (meters, kilometers, miles, feet, inches), weight (kilograms, pounds, ounces, grams) and temperature (Celsius, Fahrenheit, Kelvin) are all supported, with conversions calculated instantly as you type.
Why is temperature conversion different from the others?
Length and weight use simple multiplication (a fixed ratio), but temperature scales have different zero points, so conversions require addition/subtraction as well — that's why Celsius, Fahrenheit and Kelvin need their own formulas.
Can I convert between categories, like length to weight?
No — each category (length, weight, temperature) is a separate, compatible unit system. You can only convert within the same category.
