Millijoules per square centimeter to µW·s per square centimeter
Type a value in mJ/cm² to get it in µW·s/cm² instantly.
10,000µW·s/cm²
That's 2× as strong as a dose that inactivates most viruses, while a sunburn dose for fair skin is 2.5× stronger.
Convert the other way: µW·s/cm² to mJ/cm²
What it means
How strong a dose is that?
Dose = irradiance × time. Germicidal doses are at 254 nm; sunburn references are erythema-weighted, so they do not compare directly with disinfection.
The math
How to convert mJ/cm² to µW·s/cm²
To convert millijoules per square centimeter to µW·s per square centimeter, multiply by 1,000.
Example: 10 mJ/cm² × 1,000 = 10,000 µW·s/cm².
In the other direction, 1 µW·s/cm² = 0.001 mJ/cm².
