Length conversion

Feet to Metres (ft to m)

Convert a length in decimal feet to metres for a room plan or measurement list. Combine any separate inches into decimal feet before entering them.

1 ft = 0.3048 m — the calculator keeps the stored factor; this summary may be rounded.

Enter 6.5 for six feet six inches. Typing 6.6 means six and six tenths of a foot, a different length.

How to convert by hand

Reference relationship (display may be rounded)

1 ft = 0.3048 m

  1. Multiply the amount in feet by the number of metres per unit.
  2. Use the calculator for the stored precision; copying a short displayed factor introduces extra rounding.
  3. Round the result to suit your measurement, after completing the calculation.

About feet and metres

Convert each measured dimension separately. A width stays a width and a diagonal stays a diagonal; changing units does not turn a product’s nominal size into a measured size.

Foot

US / Imperial

Twelve inches, or exactly 0.3048 metres. This converter uses the international foot, not the historical US survey foot.

Commonly used for: A person’s height, room lengths and altitude readings.

Metre

Metric (SI)

The SI base unit of length, defined by the distance light travels in vacuum in 1/299,792,458 of a second.

Commonly used for: Room dimensions, fabric lengths and construction measurements.

Questions

How do I enter a height given in feet and inches?

Divide the inch part by 12 and add it to the feet. For example, five feet six inches is 5.5 feet. Enter that decimal value, without quote marks or a separate inches field.

How do I convert metres back to feet?

Enter the value in the metres field above to work backwards, or open the Metres to Feet converter. This uses the stored factors rather than dividing by a rounded number copied from the chart.

Why might the chart and calculator show different decimal places?

The chart uses a compact rounded display. The editable calculator can show up to six decimal places and uses the factors or temperature formulas stored in the library. More displayed digits do not make the original measurement more precise.

Precision and source

The calculator uses stored conversion factors and temperature formulas, then rounds the result for display. A short decimal in a chart is not a claim of exactness. For a calculation with several steps, keep as much precision as the original measurement supports and round at the end.
