1 nch equals 25.4 mm.
The unit “nch” stands for nanoinch, which is one-billionth of an inch. Converting 1 nanoinch to millimeters involves multiplying by the inch-to-millimeter conversion factor and adjusting for the nano scale, resulting in 25.4 nanometers or 0.0000254 millimeters.

Conversion Formula
To convert nanoinches (nch) to millimeters (mm), multiply the nch value by 0.0000000254. This factor comes from converting inches to millimeters (1 inch = 25.4 mm), then scaling down by one billion because 1 nch = 10⁻⁹ inch.
Step-by-step:
- 1 inch = 25.4 mm
- 1 nch = 1 × 10⁻⁹ inch
- Therefore, 1 nch = 25.4 × 10⁻⁹ mm = 0.0000000254 mm
Conversion Example
- Convert 5 nch to mm:
- Multiply 5 × 0.0000000254
- Result: 0.000000127 mm
- This means 5 nanoinches equal 0.000000127 millimeters.
- Convert 10 nch to mm:
- 10 × 0.0000000254 = 0.000000254 mm
- So, 10 nanoinches is 0.000000254 millimeters.
- Convert 0.5 nch to mm:
- 0.5 × 0.0000000254 = 0.0000000127 mm
- Half nanoinch equals 0.0000000127 millimeters.
- Convert 20 nch to mm:
- 20 × 0.0000000254 = 0.000000508 mm
- 20 nanoinches equal 0.000000508 millimeters.

Conversion Definitions
nch (nanoinch): A nanoinch is a unit of length measuring one-billionth (10⁻⁹) of an inch. It’s used in contexts requiring extremely fine precision, like semiconductor manufacturing or nanoscale engineering. Since an inch equals 25.4 millimeters, a nanoinch corresponds to approximately 0.0000000254 millimeters.
mm (millimeter): Millimeter is a metric unit of length equal to one-thousandth (10⁻³) of a meter. It’s widely applied in engineering, construction, and everyday measurements. One millimeter equals 0.03937 inches, or 1,000,000 nanoinches, bridging imperial and metric systems at tiny scales.
Conversion FAQs
Why does converting 1 nch to mm result in such a small number?
Because a nanoinch is one-billionth of an inch, its size is extremely tiny. Since millimeters are much larger, converting 1 nch to mm involves multiplying by a very small factor (25.4 × 10⁻⁹), producing a minuscule result. This reflects the nanoscale length of a nanoinch.
Is the conversion factor between nch and mm always constant?
Yes, the conversion factor is constant because both nch and mm are based on fixed definitions of length units. 1 inch is defined as exactly 25.4 millimeters, and 1 nanoinch is exactly one-billionth of an inch, so the factor 0.0000000254 mm per nch never changes.
Can I use this conversion for everyday measurements?
No, nanoinches are mainly relevant in highly precise fields like nanotechnology or semiconductor fabrication. Everyday measurements use larger units like millimeters or inches. Using nanoinches for typical lengths would be impractical due to their extremely small size.
How to convert nch to mm without a calculator?
Since 1 nch equals 0.0000000254 mm, you need to multiply the nch value by this factor. Without a calculator, approximating this is difficult due to the tiny scale, but knowing it’s 25.4 nanometers can help if you think in nanometers rather than millimeters.
What industries require converting between nch and mm?
Industries like semiconductor manufacturing, nanotechnology research, and microfabrication often convert between nanoinches and millimeters. Accurate length measurements at the nanoscale are critical in these fields, so converting between imperial nanoscale units and metric units is common.
