Meters to Inches
Quick answer: 1 m = 39.37008 in. To convert, multiply the m value by 39.37008; to go back, divide.
One meter is 39.3701 inches — exact, because an inch is defined as 25.4 mm (1,000 ÷ 25.4). Screen sizes, waistlines and US product dimensions are quoted in inches; metric specs and site measurements in meters. Multiply meters by 39.3701; divide the result by 12 for feet.
The formula
in = m × 39.370079 · m = in ÷ 39.370079

| 0.25 m | 9.843 in | 0 ft 9.8 in |
| 0.5 m | 19.685 in | 1 ft 7.7 in |
| 0.75 m | 29.528 in | 2 ft 5.5 in |
| 1 m | 39.37 in | 3 ft 3.4 in |
| 1.25 m | 49.213 in | 4 ft 1.2 in |
| 1.5 m | 59.055 in | 4 ft 11.1 in |
| 1.75 m | 68.898 in | 5 ft 8.9 in |
| 2 m | 78.74 in | 6 ft 6.7 in |
| 2.5 m | 98.425 in | 8 ft 2.4 in |
| 3 m | 118.11 in | 9 ft 10.1 in |
| 5 m | 196.85 in | 16 ft 4.9 in |
1.25 m to in: 49.213 in
1.25 m = 49.213 in — 4 ft 1.2 in. Working: 1.25 × 39.37008 = 49.2126.
1.25 meters is a very human size: the average height of a 7–8-year-old, the minimum rider height on many theme-park rides (posted as 125 cm / 49 in), a typical kitchen worktop-to-cabinet span, and a little more than a single bed's width. In inches that is 49.2 in — 4 ft 1 in.
The other way: in to m
| in | m |
|---|---|
| 1 in | 0.025 m |
| 2 in | 0.051 m |
| 5 in | 0.127 m |
| 10 in | 0.254 m |
| 12 in | 0.305 m |
| 15 in | 0.381 m |
| 20 in | 0.508 m |
| 25 in | 0.635 m |
| 50 in | 1.27 m |
| 100 in | 2.54 m |
Common mistake
Using 40 in/m as a shortcut in precise work — the 1.6% error is 3 inches over 5 m. Use 39.37 for anything measured.
Frequently asked questions
Is the conversion exact?
Yes — the factor follows from the legal definition of the units (1 in = 25.4 mm and 1 ft = 0.3048 m), so the only rounding is in the last decimal place shown.
How do I convert a different value?
Use the m to in converter for any number, or the length conversion guide for every length unit and formula in one place.
