Frequently asked questions

How accurate are the conversions?

Conversions use standard, internationally recognized conversion factors and full floating-point precision, so results are accurate to many decimal places.

Which units are supported?

Length (meters, feet, inches, kilometers, miles, and more), weight (kilograms, pounds, ounces, grams), and temperature (Celsius, Fahrenheit, Kelvin).

Can I convert cooking measurements like cups or tablespoons?

Not currently — this tool focuses on length, weight, and temperature. Volume/cooking units may be added in the future.

Why does temperature conversion work differently from the others?

Length and weight are simple multiplication (a ratio), but temperature scales have different zero points, so Celsius/Fahrenheit/Kelvin conversions use an offset formula instead of a simple ratio.
