14 tools in this collection — free, instant, and private in your browser.
Length and distance converters translate measurements between the metric and imperial systems, as well as within each system. Whether you are reading a foreign product specification, following a recipe from another country, interpreting a map, or working on a construction project, being able to move fluently between inches, centimeters, feet, meters, miles, and kilometers is a practical everyday skill these tools make instant.
The most common conversions are between the two dominant global systems: metric, used almost everywhere, and imperial, still standard in the United States for everyday measurement. Centimeters to Inches and the reverse cover body measurements, clothing sizes, and screen sizes. Meters to Feet and Feet to Meters handle room dimensions, ceiling heights, and athletic distances. Kilometers to Miles and Miles to Kilometers are essential for driving directions, running plans, and travel.
Within-system conversions are also common. Inches to Feet and Feet to Inches come up in carpentry and interior design. Inches to Millimeters matters in engineering and hardware specifications where precision is critical and millimeters are the standard unit. Meters to Yards and Yards to Meters arise in fabric measurement and American football contexts.
The general-purpose Length Converter lets you pick any input and output unit from a single interface, which is convenient when you are dealing with less familiar units or need to do several different conversions in one session.
For most everyday needs, pick the dedicated converter that matches your specific pair of units for the fastest experience. Use the general Length Converter when your units are not covered by a dedicated page or when you want to compare several conversions side by side.

Frequently asked questions
- How many centimeters are in an inch?
- One inch equals exactly 2.54 centimeters. This is the defined conversion factor, not an approximation. To convert inches to centimeters, multiply by 2.54. To go the other way, divide by 2.54 or multiply by approximately 0.3937.
- What is the difference between meters and yards?
- A meter is slightly longer than a yard. One meter equals approximately 1.0936 yards, or one yard equals about 0.9144 meters. In practice they are close enough that the difference is small over short distances, but it compounds over longer spans, so always convert when precision matters.
- When would I need millimeters instead of centimeters or inches?
- Millimeters are the standard unit for tight-tolerance work in engineering, machining, hardware, and electronics. Bolt diameters, drill bit sizes, and printed circuit board clearances are all specified in millimeters. For everyday measurement like room dimensions or body height, centimeters or inches are more practical.
