Metric to imperial — instantly and accurately
Meters dominate in science, architecture and most of the world; feet remain the everyday unit in the US. Converting between them comes up constantly: ceiling heights, running distances, real-estate listings, swimming pools and building specs. This calculator does the conversion in one step: 1 m = 3.28084 ft.
The formula
ft = m × 3.28084
- m — the length in meters.
- ft — the equivalent length in feet.
- 3.28084 — 1 ÷ 0.3048; the reciprocal of the exact foot-to-meter conversion.
Alternatively: ft = m ÷ 0.3048.
Worked example
Using the default of 2 m:
- Multiply by 3.28084: 2 × 3.28084 = 6.562 ft.
- In feet-and-inches: 6′ + (0.562 × 12) = 6′6.74″.
So 2 m ≈ 6.56 ft (or 6′6¾″).

History & standards
The meter was introduced in revolutionary France in 1795 and defined as one ten-millionth of the distance from the equator to the North Pole. Since 1983 it has been defined by the speed of light: the distance light travels in a vacuum in exactly 1/299,792,458 seconds. The foot predates metric systems by millennia; the International Yard and Pound Agreement of 1959 fixed 1 ft = 0.3048 m exactly, tying the imperial foot to the SI. NIST retired the slightly different US survey foot in 2023; the international foot is now the sole US legal definition.
Common applications
- Ceiling & building heights. European buildings list floor heights in meters; US construction uses feet.
- Athletics. Track events use meters; US audiences often need the feet equivalent (100 m ≈ 328 ft).
- Swimming pools. Olympic pools are 50 m = 164 ft; US pools are often 25 yds.
- Aviation. Runway lengths are given in meters internationally, feet in the US.
- Real estate. European property descriptions list room dimensions in meters; US buyers need feet.
Reverse conversion
To convert feet back to meters, multiply by 0.3048: m = ft × 0.3048. Use the feet to meters calculator.
Limitations & gotchas
- Displayed precision. The calculator shows 3–4 decimal places. The conversion factor 3.28084 is itself a rounded approximation of 1÷0.3048; the underlying calculation is exact.
- Feet-and-inches output. The calculator returns decimal feet. For a feet-and-inches breakdown, multiply the decimal part by 12 (e.g. 6.562 ft → 6′ + 0.562×12 = 6.74″ → 6′6.74″).
- US survey foot (deprecated 2023). The difference from the international foot is <2 ppm — negligible for everyday purposes.

FAQs
Multiply by 3.28084: ft = m × 3.28084. For example, 2 m × 3.28084 = 6.562 ft. The factor 3.28084 comes from the exact definition 1 ft = 0.3048 m, giving 1/0.3048 = 3.28084…
1 m = 1 ÷ 0.3048 ≈ 3.28084 ft. More precisely, 3.280839895… ft.
2 × 3.28084 = 6.562 ft (approximately 6′6.74″).
1.8 × 3.28084 ≈ 5.906 ft (approximately 5′10.87″).
ft = m × 3.28084. Equivalently: ft = m ÷ 0.3048.
The 1959 International Yard and Pound Agreement defined 1 inch = 25.4 mm exactly. Since 1 ft = 12 in, 1 ft = 12 × 25.4 mm = 304.8 mm = 0.3048 m. This makes the conversion exact — 3.28084 is the rounded form of the infinite decimal 1 ÷ 0.3048.
