Feet and Inches to Metres and Centimetres Calculator

Live answer1.778 m177.8 cm · 5 ft 10 in = 70 in total

Feet (ft)Enter the whole-foot part of the imperial measurement.Inches (in)Enter the inch part. Values above 12 are accepted and converted through total inches.

Live result1.778 m177.8 cm · 5 ft 10 in = 70 in total

Formula used

Total inches = feet × 12 + inches. Metres = total inches × 0.0254. Centimetres = metres × 100.

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

Assumptions used

What this answer assumes

Exact inch-to-metre basis. Round only after choosing the precision your job or record needs.

1 foot is treated as exactly 12 inches.
The international inch is exactly 25.4 millimetres, which is 0.0254 metres.
Results are shown to practical decimal precision; keep more decimals for engineering records if required.
This is a length conversion only. It does not add construction waste, cutting allowance or material tolerance.

Master’s Tip

How to use the result well

Master’s Tip: for building and material orders, record the original imperial dimensions and the converted metric dimensions together. When cuts, kerfs, tolerances or offcuts matter, round purchase quantities upward rather than trusting a bare converted length.

What-if check

Cutting and tolerance allowance

The conversion is exact, but real materials often need a little extra for cuts, kerfs and tolerance. These rows show the metric effect of adding small imperial allowances.

Allowance added	Metres	Centimetres
No allowance	1.778 m	177.8 cm
+0.5 in	1.791 m	179.1 cm
+1 in	1.803 m	180.3 cm
+2 in	1.829 m	182.9 cm

Visual proof

Imperial to metric length bar

The blue bar represents the entered length after feet are converted into total inches and then multiplied by exactly 0.0254 metres per inch.

Visual grid

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.

Space calculations turn a real surface, room, run or volume into cells, edges and allowances that can be quoted, ordered or checked.

Inputs

Feet: 5 ft
Inches: 10 in

Method

Total inches = feet × 12 + inches. Metres = total inches × 0.0254. Centimetres = metres × 100.

5 ft 10 in = 5 × 12 + 10 = 70 total inches. 70 × 0.0254 = 1.778 metres. 1.778 × 100 = 177.8 centimetres.

Assumptions

1 foot is treated as exactly 12 inches.
The international inch is exactly 25.4 millimetres, which is 0.0254 metres.
Results are shown to practical decimal precision; keep more decimals for engineering records if required.
This is a length conversion only. It does not add construction waste, cutting allowance or material tolerance.
