Inches to Meters (in to m) Converter
1 inch equals exactly 0.0254 meters — multiply the number of inches by 0.0254 to convert. The inch is internationally defined as 2.54 cm, which is 0.0254 m, so this factor is exact.
The formula
To convert inches to meters, multiply by 0.0254:
meters = inches × 0.0254
For example, 100 in × 0.0254 = 2.54 m. To reverse it, divide meters by 0.0254 (or multiply by 39.370079).

| 2 | 0.0508 |
| 3 | 0.0762 |
| 5 | 0.127 |
| 10 | 0.254 |
| 25 | 0.635 |
| 50 | 1.27 |

| 1000 | 25.4 |
Worked example
Say a beam is 120 inches long and you need meters for an engineering drawing. Multiply: 120 × 0.0254 = 3.048 m. Reversing, 3.048 ÷ 0.0254 = 120 inches. A 60-inch span is 60 × 0.0254 = 1.524 m, and a 240-inch wall is 240 × 0.0254 = 6.096 m. Since the factor is exactly 0.0254, each added inch contributes another 0.0254 meters, so 100 inches is 2.54 m and 1,000 inches is 25.4 m. This is the conversion behind many international product specs, where component sizes are quoted in inches but the overall dimensions must appear in meters on the plans your team files. Reverse it by dividing any meter value by 0.0254 to recover inches, so 3.048 m returns 120 inches and 1.524 m returns 60 inches.
