DNA/RNA Concentration Calculator
Convert A260 to DNA/RNA concentration and total yield; report A260/A280 and A260/A230 purity ratios.
Calculator
Formula
c=A₂₆₀·factor·dilution
Assumptions and limits
- Standard 1 cm path-length conversion factors are used; instrument path-length correction must already be applied.

Frequently asked questions
Are my inputs uploaded?
No. This calculator runs locally in your browser. Inputs are placed in a URL only when you explicitly copy a share link.
Why are units converted first?
Canonical units prevent scale errors when inputs use mixed units. The result is converted back to your selected output unit afterward.
Does the result replace professional judgment?
No. The result applies only to the stated model and assumptions. Qualified people should review high-risk engineering, medical, or laboratory decisions.
