Formula used

Total inches = feet × 12 + inches. Centimetres = total inches × 2.54. Metres = centimetres ÷ 100. Planning centimetres = centimetres + optional allowance.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Best for height records, product dimensions, classroom worksheets, clearance notes, fit checks and job records where the centimetre answer must stay tied to the original imperial measurement.

  • 1 foot is exactly 12 inches.
  • The international inch is exactly 2.54 centimetres, so the conversion factor is exact.
  • The optional allowance is a separate planning note; it does not change the measured feet-and-inches conversion.
  • Round only after deciding the record, classroom, clothing, clearance, drawing or job tolerance needed.

Master’s Tip

How to use the result well

Master’s Tip: keep the original feet-and-inches measurement on the printed record. The centimetre result is exact, but the source dimension prevents mix-ups when a height chart, product listing, drawing or site note still uses imperial units.

Method

Total inches = feet × 12 + inches. Centimetres = total inches × 2.54. Metres = centimetres ÷ 100. Planning centimetres = centimetres + optional allowance.

  1. For 5 ft 10 in, total inches = 5 × 12 + 10 = 70 in. Centimetres = 70 × 2.54 = 177.8 cm. Metres = 177.8 ÷ 100 = 1.778 m. With a 2 cm allowance, the planning length is 179.8 cm.

Assumptions

  • 1 foot is exactly 12 inches.
  • The international inch is exactly 2.54 centimetres, so the conversion factor is exact.
  • The optional allowance is a separate planning note; it does not change the measured feet-and-inches conversion.
  • Round only after deciding the record, classroom, clothing, clearance, drawing or job tolerance needed.
