3.93700787e-8inch

inch = nm × 3.93700787e-8

nm = inch × 25,400,000

Example: 10 nm = 10 × 3.93700787e-8 = 3.93700787e-7 inch.

Express both nm and inch in the same base unit m (meter), then cancel the shared base unit.

1
Rewrite nm in the base unit
$1 nm = 1 \times 1 0^{- 9} m$
2
Rewrite inch in the base unit
$1 inch = 0.0254 m$
3
Forward conversion
$1 nm = \frac{1 \times 1 0 ^{- 9} m}{0.0254 m} \times 1 inch = \frac{1 \times 1 0 ^{- 9}}{0.0254} inch = 3.93700787 \times 1 0^{- 8} inch$
4
Reverse conversion
$1 inch = \frac{0.0254 m}{1 \times 1 0 ^{- 9} m} \times 1 nm = \frac{0.0254}{1 \times 1 0 ^{- 9}} nm = 25, 400, 000 nm$
