Kilobases to nanometers

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

340nm

That's 50× as long as a PCR primer, while a plasmid is 5× longer. Stretched out, that would be about 0.00034 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 kb to nm

To convert kilobases to nanometers, multiply by 340.

Example: 1 kb × 340 = 340 nm.

In the other direction, 1 nm = 0.00294118 kb.
