Formula
Total inches = centimetres ÷ 2.54. Decimal feet = total inches ÷ 12. Feet-and-inches = floor(total inches ÷ 12) feet plus remaining inches. Planning feet use (centimetres + allowance centimetres) ÷ 2.54 ÷ 12.

This result measures part of the space you live in
Length, area, volume and material estimates are grid problems too: measure the space, account for edges and allowances, then turn the pattern into a number you can use.

Inputs
- Centimetres
- 180 cm
- Optional allowance
- 0 cm
- Inch rounding increment
- 0.125 in
Method
Total inches = centimetres ÷ 2.54. Decimal feet = total inches ÷ 12. Feet-and-inches = floor(total inches ÷ 12) feet plus remaining inches. Planning feet use (centimetres + allowance centimetres) ÷ 2.54 ÷ 12.
- For 180 cm, total inches = 180 ÷ 2.54 = 70.8661 in. Decimal feet = 70.8661 ÷ 12 = 5.9055 ft. The feet-and-inches split is 5 ft 10.8661 in, which rounds to about 5 ft 10.875 in when using the nearest eighth inch.
Assumptions
- The conversion uses the exact international inch definition: 1 inch = 2.54 centimetres, so 1 foot = 30.48 centimetres.
- The main decimal-feet result is calculated before any allowance is added.
- Feet-and-inches are shown as a practical reading; decimal feet remains the clean numeric output for spreadsheets and formulas.
- Rounding applies only to the displayed inch split. It does not change the exact centimetre input.

Worked example
For 180 cm, total inches = 180 ÷ 2.54 = 70.8661 in. Decimal feet = 70.8661 ÷ 12 = 5.9055 ft. The feet-and-inches split is 5 ft 10.8661 in, which rounds to about 5 ft 10.875 in when using the nearest eighth inch.
Professional note
Master’s Tip: write both decimal feet and feet-and-inches when a measurement may move between spreadsheets and people on site. Decimal feet is easier to calculate with; feet-and-inches is usually easier to read aloud.

Questions
How do I convert centimetres to feet?
Divide centimetres by 30.48 to get decimal feet. Equivalently, divide by 2.54 to get inches, then divide inches by 12.
What is 180 cm in feet?
180 cm is about 5.9055 decimal feet, or 5 ft 10.866 in before practical inch rounding.
Why does the calculator show decimal feet and feet-and-inches?
Decimal feet is useful for spreadsheets, formulas and engineering-style arithmetic. Feet-and-inches is easier for human height, cutting and everyday measurement notes.
Is 1 foot exactly 30.48 cm?
Yes. Because 1 inch is exactly 2.54 cm and 1 foot is 12 inches, 1 foot equals exactly 30.48 cm.
What should I print for a cm-to-feet measurement record?
Print the centimetres entered, decimal feet, total inches, feet-and-inches split, rounding increment, allowance if used, formula, date, page URL and notes area.
Calculation note
Centimetres and feet belong to different measurement families, so the safest conversion record names the exact inch bridge, keeps the decimal-feet number visible and gives a feet-and-inches reading for human use.
The inch is the exact bridge
Modern metric-to-foot conversion is stable because the international inch is defined as exactly 2.54 centimetres. From there, feet are just twelve exact inches.
Decimal feet and spoken measurements serve different jobs
A spreadsheet prefers one decimal number, while a person measuring height or cutting timber often thinks in feet and inches. Showing both prevents transcription mistakes.
Printed records make rounding visible
A measurement note should say whether inches were rounded to an eighth, quarter or whole inch. Otherwise two people can use the same centimetre value and file different-looking answers.
