Length Converter

What is a Length Converter?

A length converter instantly translates a measurement from one unit into all others at the same time. Type any value and the remaining fields update automatically. Useful when working between metric and imperial units, reading blueprints, or following international recipes and patterns.

How It Works

Every unit converts through meters as the base:

1 inch = 0.0254 m
1 foot = 0.3048 m
1 yard = 0.9144 m
1 mile = 1,609.344 m
1 km = 1,000 m
1 cm = 0.01 m
1 mm = 0.001 m

Example

A marathon is 26.2 miles. In other units:

  • 26.2 mi x 1609.344 = 42,164.8 m
  • = 42.165 km
  • = 138,336 ft

Tips

  • A quick mental shortcut: 1 inch is roughly 2.54 cm. Multiply centimeters by 0.4 to get a close inch estimate.
  • 1 foot = 12 inches = 30.48 cm. For height conversions, remember 6 feet is about 183 cm.
  • 1 kilometer is about 0.621 miles. A 5K race is roughly 3.1 miles.

Frequently Asked Questions

How many feet are in a meter?

There are approximately 3.281 feet in one meter. Conversely, one foot equals 0.3048 meters exactly (this is the defined international value).

How many centimeters are in an inch?

Exactly 2.54 centimeters. This is a defined value, not an approximation. So 1 inch = 2.54 cm and 1 cm = 0.3937 inches.

What is the difference between a yard and a meter?

A yard is 0.9144 meters, so a meter is about 9% longer than a yard. In practical terms, 100 yards (a football field) is about 91.4 meters.

How many miles is a kilometer?

One kilometer equals 0.621371 miles. To convert kilometers to miles quickly, multiply by 0.6 for a rough estimate, or use this converter for the exact value.
