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.
Convert the other way: nm to bp
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.
