How to Convert Inches to Meters

Tape measures can be used to measure units of length, and a calculator can be used to convert to another unit

Convert inches to meters with this simple formula:

meters = inches × 0.0254

Converting an inch length measurement to a meter measurement involves multiplying the length by the conversion ratio to find the result. One inch is equal to 0.0254 meters, so to convert simply multiply by 0.0254.

For example, here's how to convert 5 inches to meters using the formula above.
5" = (5 × 0.0254) = 0.127 m

Our inch fraction calculator can add inches and meters together and it also automatically converts the results to US customary, imperial and SI metric values.

Inches and meters are both units used to measure length. Learn more about length and find more length measurement conversion calculators. Inches are an imperial measurement and can be abbreviated as in, for example 1 in. Meters are a metric measurement and can be abbreviated as m, for example 1 m. Learn more about the metric system, including the common unit prefixes and how to convert between metric units.

The meter is the primary unit of length in the metric system. It's equal to 100 centimeters or 39.37 inches. Internationally it is actually spelled metre. It was first defined 1793 as 1/10,000,000 the length from the equator to the North Pole. The current definition of a meter, adopted in 1983, is the distance light travels in 1/299,792,458 seconds and was adopted to in 1983.

The actual length of an inch has varied because of variances of the length of a foot. Throughout history it has been equal to 1/12 - 1/16 of a foot, but there are now exactly 12 inches in a foot. In 1959 the world agreed to the exact length of the national yard, .9144 meters. As such a foot is equal to .3048 meters and an inch is equal to 2.54 centimeters.

A quarter is .955" in diameter, which is just smaller than 1"

The standard ruler has 12", and metric combinations have 30 cm. Inches are also often measured using tape measures which commonly come in lengths from 6' - 35'. Other types of measuring devices include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs. If you need a ruler you can also download and print our free printable rulers which include both imperial and metric measurements.

Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

Here is a list of some of the common metric prefixes:

  • “kilo” – 1,000x larger
  • “hecto” – 100x larger
  • “deca” – 10x larger
  • “deci” – 10x smaller
  • “centi” – 100x smaller
  • “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”
The u in Until refers to the base unit.
