How this is calculated

Formula:

meters = inches * 0.0254

In plain language:

An inch is exactly 0.0254 metres. The calculator uses metres as the base unit so you can also view the same value as centimetres, millimetres, or feet.

The formula is always visible so you can verify the math and explain your numbers to anyone who asks.

Inch to meter explained

An inch is defined as 0.0254 metres. This calculator converts inches to metres and back, while also showing centimetres, millimetres, and feet so you can report the same dimension in whichever unit your audience prefers.

How the conversion works

The inch-to-metre factor is exact:

\text{m} = \text{in} \times 0.0254

Reverse it to go back to inches:

\text{in} = \dfrac{\text{m}}{0.0254}

Centimetres and millimetres ride on the metre base: $\text{cm} = \text{m} \times 100$ and $\text{mm} = \text{m} \times 1{,}000$ .

Units and conversions

Unit	Symbol	Relation
Inch	in	$1\,\text{in} = 0.0254\,\text{m}$
Foot	ft	$1\,\text{ft} = 12\,\text{in}$
Metre	m	base
Centimetre	cm	$1\,\text{cm} = 0.01\,\text{m}$
Millimetre	mm	$1\,\text{mm} = 0.001\,\text{m}$

Worked examples

Equipment dimension
$20\,\text{in} \times 0.0254 = 0.508\,\text{m}$ .
Metres back to inches
$1\,\text{m} \div 0.0254 = 39.3701\,\text{in}$ .
Convert inches to centimetres through metres
$60\,\text{in} \times 0.0254 = 1.524\,\text{m}$ ; $1.524\,\text{m} \times 100 = 152.4\,\text{cm}$ .

Tips and pitfalls

Keep four decimals in metres before rounding back to inches if tolerances are tight.
When drawings mix inches and feet, convert to inches first, then to metres to avoid double rounding.
For area or volume, convert each linear dimension to metres, then square or cube.
