Base pairs to nanometers

Type a value in bp to get it in nm instantly.

0.34nm

Nothing on our list is smaller: a PCR primer is 20× longer. Stretched out, that would be about 3.4×10⁻⁷ mm long.

What it means

How long is that?

Figures are for double-stranded B-DNA: 0.34 nm and about 650 daltons per base pair, and 10.5 base pairs to a turn.

The math

How to convert bp to nm

To convert base pairs to nanometers, multiply by 0.34.

Example: 1 bp × 0.34 = 0.34 nm.

In the other direction, 1 nm = 2.94118 bp.
