Convert a length or distance
Enter a value, select its current unit, and choose the destination unit. The converter supports small measurements through long travel and navigation distances. Swap the units to reverse the conversion without reselecting them.
The calculation converts the input to meters and then from meters to the requested unit. Standard exact definitions are used where they exist.
Metric and international definitions
Metric units scale by powers of ten: 1,000 millimeters equal one meter, and 1,000 meters equal one kilometer. The international yard is exactly 0.9144 meter, making an inch exactly 0.0254 meter and a mile exactly 1,609.344 meters.
A nautical mile is exactly 1,852 meters. It is based on navigation conventions and is different from the statute mile used for ordinary road distance in the United States and United Kingdom.
Precision and rounding
The displayed result uses up to 12 significant digits and switches to scientific notation for extremely large or small values. The calculation uses JavaScript double-precision numbers.
Match your final rounding to the precision of the original measurement. A value measured only to the nearest meter should not be reported as though its converted feet were known to many decimal places.
Frequently asked questions
How many feet are in one meter?
One meter equals approximately 3.28084 feet. The calculator retains more precision internally than it displays.
What definition of an inch does this converter use?
It uses the international inch, defined as exactly 0.0254 meter. A foot is 12 inches and a yard is three feet.
Is a nautical mile the same as a regular mile?
No. A nautical mile is exactly 1,852 meters, while an international statute mile is exactly 1,609.344 meters.
Does converting a rounded measurement make it more precise?
No. Conversion changes units but cannot recover precision absent from the original measurement. Round the result to suit the source data.
