3.280839895 ft

1 m = 3.280839895 ft

exact: 1250/381 ft

Step-by-step solution

  1. 1

    Set up the conversion

    Convert 1 m into ft.

    1 m→? ft1~\mathrm{m} \rightarrow ?~\mathrm{ft}
  2. 2

    Conversion factors through the base unit

    Both units are exact fractions of the base unit m — international definitions leave no rounding.

    1 m1 ft=13811250 mm\frac{1~\mathrm{m}}{1~\mathrm{ft}} = \frac{1}{\frac{381}{1250}}~\frac{\mathrm{m}}{\mathrm{m}}
    • 1 m = 1 m
    • 1 ft = 381/1250 m
  3. 3

    Multiply by the exact factor

    Multiplying by the factor ratio gives the exact result (3.280839895).

    1⋅13811250=12503811 \cdot \frac{1}{\frac{381}{1250}} = \frac{1250}{381}
  4. 4

    Result

    1 m = 3.280839895 ft.

    1 m=1250381 ft1~\mathrm{m} = \frac{1250}{381}~\mathrm{ft}

How unit conversion works

A conversion is a multiplication by an exact factor: 1 inch is defined as precisely 2.54 cm, so every imperial-to-metric conversion here stays an exact fraction — 10 lb is exactly 4.5359237 kg.

Temperature is different: the scales have different zero points, so °C, °F and K convert through an affine formula (like F = C × 9/5 + 32), done here in exact rational arithmetic.

Every factor is shown as a fraction in the steps, so you can follow the cancellation through the base unit (metre, kilogram, litre, …) instead of trusting a black box.
