The exact method behind this answer

CalculationTime keeps the method visible so the number can be checked instead of blindly trusted.

Metres = feet × 0.3048. Centimetres = metres × 100. Inches = feet × 12. Optional planning centimetres = centimetres + allowance centimetres.

Assumptions used

What this answer assumes

Exact international-foot conversion. Add allowance only after the measured length is preserved.

1 international foot is exactly 0.3048 metres.
1 foot is exactly 12 inches, and 1 inch is exactly 2.54 centimetres.
The optional allowance is added after the source feet value is converted, so measured length and planning adjustment stay separate.
This is a unit conversion only. It does not decide building tolerance, product fit, cutting waste or compliance requirements.

Master’s Tip

How to use the result well

Master’s Tip: keep the original decimal-foot measurement beside the metre and centimetre result. If the number will be used for cutting, clearance or ordering, add that allowance as a separate line rather than hiding it inside a rounded conversion.

Formula

Metres = feet × 0.3048. Centimetres = metres × 100. Inches = feet × 12. Optional planning centimetres = centimetres + allowance centimetres.

Worked example

For 6 ft, multiply 6 × 0.3048 = 1.8288 m. Convert to centimetres: 1.8288 × 100 = 182.88 cm. The same length is 6 × 12 = 72 inches.

Professional note

Regional and unit assumptions

Standard or basis: the international foot is exactly 0.3048 metres. This page uses transparent unit-conversion arithmetic based on exact international foot and inch definitions, with practical display rounding only after the exact conversion.

Assumptions and limitations

1 international foot is exactly 0.3048 metres.
1 foot is exactly 12 inches, and 1 inch is exactly 2.54 centimetres.
The optional allowance is added after the source feet value is converted, so measured length and planning adjustment stay separate.

Methodology & Accuracy

How this calculator is checked

CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.

Formula used

Metres = feet × 0.3048. Centimetres = metres × 100. Inches = feet × 12. Optional planning centimetres = centimetres + allowance centimetres.

Standard or basis

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.

Questions

How many metres are in one foot?

One international foot is exactly 0.3048 metres.

What is the formula for feet to metres?

Multiply feet by 0.3048 to convert feet to metres.

How many metres is 6 feet?

6 feet is exactly 1.8288 metres, which is 182.88 centimetres.

Can I convert decimal feet such as 5.75 ft?

Yes. Decimal feet are accepted. For example, 5.75 ft means 5 feet and 9 inches because 0.75 × 12 = 9 inches.

Should I round before or after conversion?

Convert first using the exact factor, then round the displayed result to the precision needed for the record, drawing, quote or worksheet.

Calculation note

Feet-to-metres conversion is common when imperial measurements from height records, property notes, imported plans, sports data or workshop dimensions need to be used in a metric context. The conversion is exact at the unit-definition level, but the printed record still needs sensible rounding and clear source units.

The international foot has an exact metre value

Modern international-foot conversion uses the exact relationship 1 ft = 0.3048 m. That means a result such as 6 ft = 1.8288 m is not an approximation from this calculator; only the displayed rounding changes.

Decimal feet and tape-measure inches can both matter

A spreadsheet may store 5.75 ft, while a person with a tape measure may say 5 ft 9 in. Showing feet, inches, metres and centimetres together helps prevent a quiet unit mismatch in job notes, school work or product dimensions.

Allowances should not erase the measured value

Cutting tolerance, clearance or purchasing buffer belongs after the exact conversion. The printable report keeps the original feet value, metric result, formula and optional allowance visible so the calculation can be checked later.
