Meters to Feet Converter

Meters to Feet Converter

Meters to Feet Converter bridges metric measurements and the US/UK foot for height, building dimensions, hiking elevations, and aviation altitudes. One meter equals exactly 3.280839895 feet because a foot is internationally defined as 0.3048 meters (1959 International Yard and Pound Agreement). The tool returns decimal feet for engineering, feet+inches for human-scale dimensions (height charts, ceiling heights, door clearances), and a verification table for common values. It is used by climbers reading mixed-unit topo maps, civil engineers translating European structural drawings, NBA fans converting player heights, drone pilots respecting US 400 ft ceilings expressed in metric flight logs, and aviation crews where altitudes remain in feet worldwide regardless of the metric flight plan.

d_(ft) = d_(m) × 3.280839895

Example

Convert 2 meters to feet: 2 m × 3.280839895 = 6.56167979 ft

Why does aviation still use feet for altitude when most of the world is metric?

ICAO Standard Atmosphere altitudes have used feet since the 1940s because the US led post-war commercial aviation infrastructure. ATC separation rules (1000 ft vertical at FL290 and below, 2000 ft above FL290 in non-RVSM airspace) and altimeter readouts all use feet, and changing them would require simultaneously updating thousands of charts, aircraft, and procedures globally. Russia and China use metric flight levels internally (e.g., FL3000 m = 9842 ft), which is why crews flying into Russian airspace receive a metric-to-feet conversion clearance. For ground operations and ICAO altimetry calculations, 1 m equals 3.28084 ft, so FL350 (35000 ft) is exactly 10668 m.

How is a person's height converted into feet and inches?

The tool first multiplies meters by 3.280839895 to get decimal feet. Then it extracts the integer feet portion and converts the fractional remainder to inches (multiply by 12). For example, 1.78 m = 5.840551 ft. Take the integer 5 (= 5 ft) and the remainder 0.840551 ft x 12 = 10.0866 in, rounded to 5 ft 10 in. Many height converters get this wrong by rounding inches up to 12, which would produce 5 ft 12 in instead of 6 ft 0 in. This tool checks for that edge case and rolls over correctly when inches round to 12.

Is decimal feet the same as the survey foot used in US land deeds?

No. The international foot is exactly 0.3048 m. The US survey foot, used in legal land descriptions until January 2023, is 1200/3937 m or about 0.30480061 m. The two differ by 2 parts per million (about 2 mm per kilometer). For typical residential conversions the difference is invisible: a 2400 sq ft house plan is identical either way. But for long survey lines (state plane coordinates, township sections), a 10-mile baseline can show a 20 mm discrepancy depending on which definition the original surveyor used. NIST and NOAA officially deprecated the survey foot for new applications on December 31, 2022.

How accurate are hiking and topographic elevations in feet?

USGS topo maps use 10-, 20-, or 40-foot contour intervals depending on terrain steepness. Hand-held GPS units quote elevation in feet (default in the US) or meters, with vertical accuracy typically 1.5 to 3 times worse than horizontal accuracy due to satellite geometry constraints. A consumer GPS that holds 3 m horizontal usually holds 5 to 10 m vertical, equivalent to 16 to 33 ft. For trail planning, that means a 500 m peak elevation (1640 ft) is reliable to plus or minus 16 ft on a calibrated barometric-aiding device. For surveying or aviation, use survey-grade RTK GPS which holds 2 cm vertical, equivalent to 0.07 ft.

Why is a basketball court 28 m by 15 m but US courts are 94 ft by 50 ft?

FIBA international rules specify 28 m x 15 m. NBA and NCAA courts in the US are 94 ft x 50 ft, which is 28.65 m x 15.24 m. The 65 cm difference in length is enough to affect three-point shot distance: FIBA three-point arc is 6.75 m (22.15 ft), NBA is 23 ft 9 in (7.24 m), a 16-inch gap that visibly changes shot selection. Player heights are reported in both systems: a 2.08 m forward (6 ft 9.9 in, listed as 6 ft 10 in) maps cleanly to American conventions but European media usually print the metric value first.

How does this tool handle negative or extremely large values?

Negative inputs (e.g., -100 m below sea level for Death Valley or the Dead Sea) convert correctly: -100 m = -328.084 ft. The Mariana Trench at -10994 m converts to -36070 ft. On the upper end, Mount Everest at 8848.86 m converts to 29031.69 ft. The tool handles up to IEEE-754 double-precision range, about 1.8 x 10^308, so even cosmic distances expressed in meters can be converted (though feet are rarely used at those scales). Negative or zero inputs do not produce errors, only zero or negative feet output.

What about historical or country-specific feet like the Paris foot or Roman foot?

Before 1959, dozens of national foot definitions existed: the Paris foot (pied du roi) was 0.3248 m, the Russian foot was 0.3048 m (same as international), the Spanish pie was 0.2786 m, the Roman pes was about 0.2957 m. This converter uses only the international foot (0.3048 m). For historical research, multiply your meter value by the country-specific factor: a 100 m field in Renaissance France was about 308 pieds du roi, not 328 modern feet. The 1959 redefinition eliminated this Babel of definitions for engineering use, though land deeds and historical maps still reference the older values.
