About this tool
Convert between meters, kilometers, feet, inches, and miles without hunting for the right multiplier. Every conversion routes through meters using exact international definitions, such as one foot equaling exactly 0.3048 meters, so results are precise to six decimal places rather than rounded rule-of-thumb figures.
How to use
- Type the measurement in the Amount field.
- Select the unit you are converting from in the From dropdown.
- Select the target unit in the To dropdown and read the converted result.
Frequently asked questions
What conversion factors does this tool use?
The exact international definitions: 1 foot is 0.3048 meters, 1 inch is 0.0254 meters, 1 mile is 1,609.344 meters, and 1 kilometer is 1,000 meters. Your amount is converted to meters first, then to the target unit.
How precise are the results?
Results display up to six decimal places. Because the underlying factors are exact by definition, any rounding only occurs in that final display step.
Are these US survey feet or international feet?
International feet, defined as exactly 0.3048 meters. The deprecated US survey foot differs by about 2 parts per million, which only matters in large-scale land surveying.
Can I convert between two units of the same system, like inches to feet?
Yes. Any From and To combination works, including imperial to imperial and metric to metric, since everything passes through meters as a common base.
Does the tool handle decimal input?
Yes, the Amount field accepts decimals like 5.75, and negative values convert mathematically if you need them for coordinate or offset arithmetic.
