Length Converter

This meters to feet converter changes any length unit into any other: miles, yards, feet, inches, kilometers, meters, centimeters, millimeters, nautical miles, light-years, points, and picas. Type a number, pick the units, and the answer appears right away. Everything runs in your browser, so nothing you type leaves your device.

How length conversion works

Length units are fixed multiples of each other, so the tool changes your value to meters first, then to the unit you want. It uses these exact factors:

  • 1 inch = 2.54 cm exactly
  • 1 foot = 0.3048 m
  • 1 yard = 0.9144 m
  • 1 mile = 1.609344 km
  • 1 nautical mile = 1,852 m exactly
  • 1 light-year = 9,460,730,472,580,800 m
  • 1 point = 1/72 inch
  • 1 pica = 12 points

Results are rounded to 6 decimal places. Very large results, such as light-year conversions, are shown in full instead of being rounded.

Solved example: 5 km to miles

How far is a 5 km run in miles? Here is the math, step by step.

  1. The tool uses 1 km = 0.621371 miles (rounded to 6 decimals).
  2. Multiply: 5 × 0.621371 = 3.106855.
  3. Round to 6 decimals: 3.106855.

Answer: 5 km = 3.106855 miles.

Limits: what this converter does not do

  • It converts straight-line lengths only. It does not measure areas, volumes, or driving distances on a map.
  • Results are rounded to 6 decimals. That is plenty for everyday use, but survey-grade work needs more care.
  • It covers the twelve units listed, including nautical miles, light-years, points, and picas. It does not cover area or volume units.

Frequently asked questions

How exact is this meters to feet converter?

Very. By definition 1 inch = 2.54 cm exactly, which makes 1 meter = 3.280839895 feet. The tool shows 3.28084, rounded to 6 decimals.

Is a yard the same as a meter?

No, but they are close. A yard is 0.9144 meters, so a meter is about 9 percent longer than a yard.

How many miles is a marathon?

A marathon is 26.2 miles, which is 42.195 kilometers. Type 26.2 into the tool to check it.

Why does the tool show so many decimals?

Small units need them. Six decimals keep conversions like millimeters to inches useful instead of rounding to zero.

Does this converter handle nautical miles and light-years?

Yes. Alongside the original eight units, the tool now converts nautical miles (1 nmi = 1,852 m exactly), light-years (1 ly = 9,460,730,472,580,800 m), points (1 pt = 1/72 inch), and picas (1 pc = 12 points). Pick any of them in the From or To lists.
