Base pairs to helical turns
Type a value in bp to get it in turns instantly.
0.09524turns
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 turns
To convert base pairs to helical turns, multiply by 0.0952381.
Example: 1 bp × 0.0952381 = 0.0952381 turns.
In the other direction, 1 turns = 10.5 bp.
