Length Converter: Convert Meters, Feet, Inches and Miles
A length converter helps translate measurements used in travel, construction plans, schoolwork and product specifications. Select the source and target units and check the displayed precision.
Convert a length measurement
- Enter the numeric measurement.
- Select the starting unit, such as feet or meters.
- Select the unit you need, such as inches or kilometers.
- Choose Convert and review the result.
- Use Swap units to reverse the conversion direction.
Supported length units
This converter includes meters, kilometers, centimeters, millimeters, miles, feet and inches. It converts through standard scale factors and rounds the displayed result.
Precision and real-world measurements
A converted number does not make an imprecise source measurement more accurate. Verify required rounding for construction, surveying, shipping or regulated specifications.
Units and exact relations
The converter supports metres, kilometres, centimetres, millimetres, miles, feet and inches. Some relations are exact by definition: one inch is 2.54 centimetres, one foot is 0.3048 metres and one mile is 1.609344 kilometres. The tool converts through these standard factors and rounds the number it shows.
Worked examples
A height of 6 feet is 1.8288 metres. A person who is 5 feet 10 inches tall is 70 inches, which is 177.8 centimetres. A 100 metre race is about 328.08 feet. A 10 kilometre run is about 6.21 miles. For feet and inches, convert the feet and the inches separately or change everything into inches first and then convert once.
Precision and mistakes
A conversion cannot make a rough measurement more exact, so measure carefully before you convert. Do not confuse millimetres with centimetres, which differ by a factor of 10, or a metre with a yard. Write the unit next to every number, and for construction, shipping or any regulated work use the precision that the specification asks for.
