Sources and Accuracy
Length conversions use the metre as the reference unit. Common imperial relationships are exact where standardized, such as 1 inch = 0.0254 metre and 1 foot = 0.3048 metre.
Displayed results are rounded for readability. The calculator keeps enough precision for everyday use and switches to scientific notation for very large or very small values. Last reviewed: 2026-05-21.
