Inches to Meters Converter (in to m)
1 in = 0.0254 m exactly. Convert inches to meters for BMI, mattress and door sizes or accessibility specs, with feet and inches shown too.
Meter (m) = Inch (in) × 0.0254
Inch (in): The inch is exactly 2.54 centimetres, a value fixed by the 1959 international yard and pound agreement. It is used in the US and UK for screen sizes, tools, pipes and body measurements.
Meter (m): The metre is the SI base unit of length. Since 1983 it has been defined as the distance light travels in a vacuum in 1/299 792 458 of a second.
| Inch (in) | Meter (m) |
|---|---|
| 1 | 0.0254 |
| 5 | 0.127 |
| 10 | 0.254 |
| 25 | 0.635 |
| 50 | 1.27 |
| 100 | 2.54 |
The BMI formula divides weight in kilograms by the square of height in meters, yet US clinics, driver's licenses and team rosters record height in inches or in feet and inches. Multiply inches by 0.0254 for meters; the factor is exact because the inch is defined as 25.4 mm.
The same conversion turns US furniture and building dimensions into metric: door heights, mattress sizes and the clearances in the ADA accessibility standards. The first chart lists adult heights from 58 to 78 inches with feet and inches beside them, plus a few round lengths.

Formula
Meter (m) = Inch (in) × 0.0254
Inch (in) = Meter (m) × 39.3700787402
Both factors come from exact definitions: 1 meter = 39.3700787402 inches and 1 inch = 0.0254 meters (shown to 12 significant digits).
Example
Two conversions worked with the same factors the converter uses:
70 in × 0.0254 = 1.778 m
1.2 m × 39.3700787402 ≈ 47.2441 in

Quick mental estimate
Divide the inches by 40: 70 in → 1.75 m, against an exact 1.778 m. Because 1 m is about 39.37 in, dividing by 40 comes out about 1.6% low, close to 3 cm on an adult height.

Inch (in): The inch is exactly 2.54 centimetres, a value fixed by the 1959 international yard and pound agreement. It is used in the US and UK for screen sizes, tools, pipes and body measurements.
Meter (m): The metre is the SI base unit of length. Since 1983 it has been defined as the distance light travels in a vacuum in 1/299 792 458 of a second.
Frequently asked questions
What is my height in meters for a BMI calculation?
Convert your height to total inches (feet × 12 + inches), then multiply by 0.0254. For 5 ft 9 in that gives 69 in, or 1.7526 m. The BMI calculator also accepts feet and inches directly.
How wide must an accessible doorway be in meters?
The 2010 ADA Standards require a clear opening of at least 32 in, which is 0.8128 m; the standards print the metric figure as 815 mm. Clear width is measured between the face of the open door and the stop, not across the frame.
How many meters is 100 inches?
Exactly 2.54 m, a handy check value: every 100 inches adds 2.54 m. A 100-inch projector screen is measured on the diagonal, so it spans 2.54 m corner to corner.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
