Formula
Total centimetres = metres × 100 + centimetres. Total inches = total centimetres ÷ 2.54. Feet = floor(total inches ÷ 12). Remaining inches = total inches − feet × 12.

Total centimetres = metres × 100 + centimetres. Total inches = total centimetres ÷ 2.54. Feet = floor(total inches ÷ 12). Remaining inches = total inches − feet × 12.
This is the method behind the answer, so the result can be checked rather than simply trusted.What-if check
Small metric allowances
The unit conversion is exact, but workshop measurements often need a tolerance or safe-side allowance. These rows show how small centimetre additions affect the feet-and-inches reading.
| Allowance added | Feet | Remaining inches |
|---|---|---|
| No allowance | 5 ft | 10.08 in |
| +0.5 cm | 5 ft | 10.28 in |
| +1 cm | 5 ft | 10.47 in |
| +2 cm | 5 ft | 10.87 in |
Visual proof
Metric to imperial length bar
The blue bar represents the entered metric length after metres and centimetres are combined, then divided by exactly 2.54 centimetres per inch.

Worked example
1 m and 78 cm = 178 cm total. 178 ÷ 2.54 = 70.0787 total inches. 70.0787 ÷ 12 gives 5 whole feet with 10.08 inches remaining, so the practical result is about 5 ft 10.08 in.
Professional note
Master’s Tip: when converting metric plans for imperial tools or materials, keep the original metric dimension beside the converted feet-and-inches result. For cutting lists and purchase quantities, round in the safe direction after checking kerf, tolerances and supplier sizes.
Regional and unit assumptions
Standard or basis: the international inch is exactly 25.4 mm, so 1 inch is exactly 2.54 cm and 1 foot is exactly 30.48 cm. This page uses transparent unit-conversion arithmetic based on that exact relationship.
Assumptions and limitations
- The international inch is exactly 25.4 millimetres, which is exactly 2.54 centimetres.
- 1 foot is treated as exactly 12 inches.
- The feet value is the whole-foot part; remaining inches are shown with practical decimal precision.
- This is a length conversion only. It does not add cutting allowance, product tolerance or construction waste.

Questions
How many feet and inches is 1.78 metres?
1.78 metres is 178 centimetres. Divide by 2.54 to get about 70.08 inches, which is 5 feet and 10.08 inches.
What is the formula for metres and centimetres to feet and inches?
Convert everything to centimetres, divide by 2.54 to get total inches, then divide by 12 for whole feet and remaining inches.
Is one foot exactly 30.48 centimetres?
Yes. Because one inch is exactly 2.54 centimetres and one foot is 12 inches, one foot is exactly 30.48 centimetres.
Should I round the inches result?
For display, rounding to one or two decimal places is usually enough. For workshop or engineering records, keep the original metric value and round only after choosing the required tolerance.
Can centimetres be more than 100 in the input?
Yes. The calculator converts everything through total centimetres, so 1 m 125 cm is treated as 225 cm total.
Calculation note
Metric-to-imperial conversion remains useful where plans, product sheets, tape measures or workshop habits use different unit systems. A clear reverse converter keeps the metric source value intact while producing a practical feet-and-inches reading.
The reverse conversion uses the same exact inch definition
The conversion from metres and centimetres back to feet and inches is deterministic because the inch has an exact relationship to the metre. Once the metric length is expressed in centimetres, dividing by 2.54 gives total inches without using a rough conversion factor.
Feet and inches are a mixed-unit display
Imperial length is often spoken as whole feet plus remaining inches rather than total inches alone. The calculator therefore separates the whole-foot part from the inch remainder so the result matches how people read heights, boards and tape measurements.
Rounding belongs at the end
Rounding too early can create small but avoidable differences in cutting lists or records. Convert from the full metric value first, then round the remaining inches to the precision required by the job.
