Frequently Asked Questions

Which unit categories are covered?+

The everyday set: length (m/ft/mi), weight (kg/lb/oz), temperature (°C/°F/K), volume (l/gal), area, speed and data sizes — metric and imperial both ways.

How is temperature different from other conversions?+

Temperature uses offset formulas, not simple multiplication — 0°C is 32°F, not 0. The converter applies the correct formula automatically.

How precise are the results?+

Conversions use standard exact factors and full floating-point precision; display rounding never affects the underlying math.

What are typical uses?+

Recipes with American units, product listings for international buyers, travel (miles vs kilometers, °F vs °C) and school physics homework.
