Frequently Asked Questions

8 units: Meters (m), Centimeters (cm), Millimeters (mm), Inches (in), Feet (ft), Yards (yd), Kilometers (km), and Miles (mi). All 8 conversions are calculated simultaneously when you type. Click any result card to copy its value to clipboard. Select the From/To units using the custom dropdowns.
Blender: 1 unit = 1 meter. Maya: 1 unit = 1 cm. 3ds Max: 1 unit = 1 inch. Unreal Engine: cm. Unity: meters. Houdini/Cinema 4D: 1 unit = 1 meter. This is why a Blender model imported to Maya can appear 100x too large always convert units when moving between software.
Conversions use exact international conversion factors: 1 inch = 0.0254 m, 1 foot = 0.3048 m, 1 yard = 0.9144 m, 1 mile = 1609.344 m. Results display up to 6 significant figures. Extremely large or small values automatically switch to scientific notation for readability.
