Frequently Asked Questions

Our converter supports length (meters, feet, inches), weight (kg, lbs, oz), volume (liters, gallons, cups), temperature (°C, °F, K), area (m², ft², acres), speed (km/h, mph), and data storage (bytes, KB, MB, GB, TB).

Our conversions use precise mathematical factors. For example, 1 inch = 2.54 cm exactly (by definition). We display up to 10 decimal places for precision. For most practical purposes, 2-4 decimal places are sufficient.

Metric (SI) uses base-10 units (meter, gram, liter) - used worldwide. Imperial uses feet, pounds, gallons - mainly US, UK (partially), Myanmar, Liberia. Metric is easier for calculations; imperial is ingrained in some countries.

Convert to a common base unit first. Example: To convert furlongs to meters, know that 1 furlong = 660 feet = 201.168 meters. Our calculator handles common and unusual units with accurate conversion factors.
