What this calculator does
This tool converts a length given in meters into two useful imperial forms: a straight decimal feet value (for example 3.28084 ft) and a practical feet-and-inches value where the inch part is rounded to a fraction you choose, such as the nearest 1/8 or 1/16 of an inch. It works with decimals and negative values, and reduces fractions to lowest terms (so 4/8 becomes 1/2).
How to use it
Type the number of meters, optionally toggle the sign with the +/- button, and pick how finely you want the inches rounded under "Fractions of an Inch: 1/". A value of 8 rounds to the nearest eighth; 16 to the nearest sixteenth, and so on up to 64ths. Press calculate to see both the decimal feet and the feet-plus-inches result.
The formula explained
One foot is exactly 0.3048 meters and one inch is exactly 0.0254 meters, so $$\text{feet} = \dfrac{\text{meters}}{0.3048}, \quad \text{total inches} = \dfrac{\text{meters}}{0.0254}$$ The whole feet are \(\lfloor \text{totalInches} / 12 \rfloor\); the remaining inches are split into a whole-inch part and a fractional part. The fraction is rounded to your denominator \(D\) with \(\text{numerator} = \text{round}(\text{frac} \times D)\), carries are handled (so you never see "12 in" or "8/8"), and the fraction is reduced with the greatest common divisor.
Worked example
For 1 meter with denominator 8: $$\text{feet} = \frac{1}{0.3048} = 3.28084 \text{ ft}$$ Total inches = \(\frac{1}{0.0254} = 39.37008\) in, giving 3 whole feet (36 in) and 3.37008 in left over → 3 whole inches and 0.37008 in. Multiplying \(0.37008 \times 8\) rounds to 3, so the fraction is 3/8. Result: 1 m = 3 ft 3 3/8 in.
FAQ
Is the conversion exact? The meter-to-foot factor is exact (1/0.3048); the decimal display is rounded to 5 places and the inch part to your chosen fraction.
What does the fraction denominator mean? It is the smallest fraction of an inch shown. 1 = whole inches, 2 = halves, 64 = sixty-fourths.
Can I enter negative meters? Yes — use the +/- button. The magnitude is converted and a minus sign is prefixed to the result.
