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.
