20 nanometers (nm) is equal to approximately 7.874 in.
Since 1 nanometer equals 3.93701 x 10-8 inches, multiplying 20 nm by this conversion factor gives the result in inches. This conversion is based on the precise relationship between nanometers and inches, where nanometers are a tiny unit commonly used in science and engineering, and inches are a standard measurement unit in the imperial system.

Conversion Formula
The formula to convert nanometers to inches is: inches = nanometers × 3.93701 × 10-8. This works because 1 nm equals 3.93701 × 10-8 inches, which is derived from dividing 1 inch (2.54 cm) by 109 to get the inch equivalent of a nanometer. For example, converting 20 nm:
- 20 nm × 3.93701 × 10-8 in/nm
- = 20 × 0.0000000393701
- = 0.000787402 inches
- which rounded to 4 decimal places gives 0.7874 inches.
Conversion Example
- Convert 10 nm:
- 10 × 3.93701 × 10-8 = 0.000393701 inches
- Result: approximately 0.3937 in
- Convert 50 nm:
- 50 × 3.93701 × 10-8 = 0.001968505 inches
- Result: approximately 1.9685 in
- Convert 100 nm:
- 100 × 3.93701 × 10-8 = 0.00393701 inches
- Result: approximately 3.9370 in
- Convert 5 nm:
- 5 × 3.93701 × 10-8 = 0.0001968505 inches
- Result: approximately 0.1969 in
