Type a value in J/m² to get it in mJ/cm² instantly.
1mJ/cm²
Nothing on our list is smaller: a dose that inactivates most viruses is 5× stronger.
Convert the other way: mJ/cm² to J/m²
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 J/m² to mJ/cm²
To convert joules per square meter to millijoules per square centimeter, multiply by 0.1.
Example: 10 J/m² × 0.1 = 1 mJ/cm².
In the other direction, 1 mJ/cm² = 10 J/m².
