Formula
Metres = centimetres ÷ 100. Total inches = centimetres ÷ 2.54. Feet = floor(total inches ÷ 12). Remaining inches = total inches − feet × 12. Rounded inches use the selected inch increment.

Inputs
- Height
- 170 cm
- Inch rounding increment
- 0.125 in
- Optional shoe / measurement allowance
- 0 cm
- Optional comparison height
- 180 cm
Method
Metres = centimetres ÷ 100. Total inches = centimetres ÷ 2.54. Feet = floor(total inches ÷ 12). Remaining inches = total inches − feet × 12. Rounded inches use the selected inch increment.
- For 170 cm, metres = 170 ÷ 100 = 1.70 m. Total inches = 170 ÷ 2.54 = 66.9291 in. That is 5 feet with 6.9291 inches remaining, commonly written as about 5 ft 6.9 in before any form-specific rounding.
Assumptions
- The conversion uses the international inch where 1 inch equals exactly 2.54 centimetres.
- Feet-and-inches output is a display format; total inches and centimetres remain visible for audit checks.
- Rounding is applied to the inch remainder for readable forms, not to the underlying centimetre input.
- Shoe, posture, hair or measurement allowance is shown as a separate planning line, not mixed into the measured height.

Worked example
For 170 cm, metres = 170 ÷ 100 = 1.70 m. Total inches = 170 ÷ 2.54 = 66.9291 in. That is 5 feet with 6.9291 inches remaining, commonly written as about 5 ft 6.9 in before any form-specific rounding.
Professional note
Master’s Tip: print the centimetre value, total inches and feet-and-inches together. If a form wants whole inches, keep the exact centimetres on the record so later conversions do not drift through repeated rounding.
Regional and unit assumptions
Standard or basis: international length conversion with 1 inch = exactly 2.54 centimetres and 1 foot = 12 inches. This is a unit-conversion and record calculator, not a medical measurement protocol or official identity-document rule.
Assumptions and limitations
- The conversion uses the international inch where 1 inch equals exactly 2.54 centimetres.
- Feet-and-inches output is a display format; total inches and centimetres remain visible for audit checks.
- Rounding is applied to the inch remainder for readable forms, not to the underlying centimetre input.
- Shoe, posture, hair or measurement allowance is shown as a separate planning line, not mixed into the measured height.
- For clinical, legal, athletic eligibility or official identity documents, follow the measurement method and rounding rule required by that organisation.

Questions
How do I convert centimetres to feet and inches for height?
Divide centimetres by 2.54 to get total inches, divide total inches by 12 for feet, then use the remainder as inches. For example, 170 cm is about 66.93 inches, or 5 ft 6.93 in.
What is 170 cm in feet and inches?
170 cm is about 5 ft 6.9 in because 170 ÷ 2.54 = 66.929 inches and 66.929 inches is 5 feet plus 6.929 inches.
Should height be rounded to the nearest inch?
Only if the form or record asks for whole inches. The calculator shows the rounding increment so exact centimetres and rounded feet-and-inches do not get confused.
Is 1 inch exactly 2.54 centimetres?
Yes. This calculator uses the exact international-inch relationship: 1 inch = 2.54 centimetres.
What should I print for a height conversion record?
Print the centimetre input, metre value, total inches, feet-and-inches result, rounding increment, optional allowance, formula, assumptions, page URL, date and notes for the form, class, team or measurement context.
Calculation note
Human height is often recorded in centimetres in metric countries and in feet-and-inches in everyday United States and United Kingdom contexts. A useful converter keeps both formats visible because height records are frequently copied between forms.
Height uses ordinary length units
The height conversion is not a special body formula. It is the same exact length conversion used for other centimetre and inch measurements, with the result formatted in a familiar feet-and-inches style.
Rounding can change the written height
A height such as 170 cm can be written as 5 ft 6.9 in, 5 ft 7 in, or 67 in depending on the form. Showing the rounding increment prevents a rounded label from replacing the measured value.
Printable records reduce repeated conversion drift
When a team, clinic, school, casting form or travel document asks for a different unit, a printout with centimetres, inches, formula and date gives the conversion a simple paper trail.
