Assumptions used

What this answer assumes

Exact feet-to-centimetres conversion. Preserve the source feet value and add tolerance separately.

  • 1 international foot is exactly 0.3048 metres, which is exactly 30.48 centimetres.
  • 1 foot is exactly 12 inches, and 1 inch is exactly 2.54 centimetres.
  • The optional allowance is added after the exact unit conversion, so measured length and planning tolerance stay separate.
  • This page is a unit conversion record. It does not decide building tolerance, clothing fit, medical height interpretation or compliance requirements.

Master’s Tip

How to use the result well

Master’s Tip: keep the source feet measurement on the printed report. If a job, height record or product dimension needs clearance, add the allowance as its own line rather than rounding the converted centimetres upward without explanation.

Formula

Centimetres = feet × 30.48. Metres = centimetres ÷ 100. Inches = feet × 12. Optional planning centimetres = centimetres + allowance centimetres.

Worked example

For 6 ft, multiply 6 × 30.48 = 182.88 cm. Divide by 100 to show 1.8288 m. The same length is 6 × 12 = 72 inches.

Professional note

Master’s Tip: keep the source feet measurement on the printed report. If a job, height record or product dimension needs clearance, add the allowance as its own line rather than rounding the converted centimetres upward without explanation.

Regional and unit assumptions

Standard or basis: the international foot is exactly 0.3048 metres, so one foot is exactly 30.48 centimetres. The calculator uses exact unit definitions and only rounds the displayed result for readability.

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

Centimetres = feet × 30.48. Metres = centimetres ÷ 100. Inches = feet × 12. Optional planning centimetres = centimetres + allowance centimetres.

Standard or basis

Standard or basis: the international foot is exactly 0.3048 metres, so one foot is exactly 30.48 centimetres. The calculator uses exact unit definitions and only rounds the displayed result for readability.

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 centimetres are in one foot?

One international foot is exactly 30.48 centimetres.

What is the formula for feet to centimetres?

Multiply the number of feet by 30.48 to convert feet to centimetres.

How many centimetres is 6 feet?

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

Can I convert decimal feet such as 5.75 ft?

Yes. Decimal feet are accepted. For example, 5.75 ft equals 175.26 centimetres and also means 5 feet 9 inches.

Should I round the feet value before converting?

No. Convert the most accurate source measurement first, then round the displayed centimetres to the precision needed for the report, quote or worksheet.

Calculation note

Feet-to-centimetres conversion is a practical bridge between imperial height, product and site measurements and metric records. The arithmetic is exact at the unit-definition level, but the useful report is the one that also preserves the source unit, rounding choice and any tolerance added after conversion.

The centimetre result comes from an exact foot definition

The modern international foot is exactly 0.3048 metres. Because one metre is 100 centimetres, one foot is exactly 30.48 centimetres. Display rounding can change how many decimals are shown, but not the conversion basis.

Decimal feet need careful reading

A value such as 5.75 ft is not 5 ft 75 in. It means 5 feet plus 0.75 of a foot, or 5 ft 9 in. Showing inches, centimetres and metres beside the original feet value helps catch that common spreadsheet and tape-measure mismatch.

Printable records prevent quiet unit mistakes

Height records, imported product dimensions, workshop cut lists and classroom worksheets all benefit from a small paper trail: source feet, exact formula, converted centimetres, optional allowance and notes. That is why the report area is part of the calculator, not an afterthought.
