convertimate UV dose (radiant exposure)

Millijoules per square centimeter to joules per square meter

Type a value in mJ/cm² to get it in J/m² instantly.

100J/m²

That's 2× as strong as a dose that inactivates most viruses, while a sunburn dose for fair skin is 2.5× stronger.

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 J/m²

To convert millijoules per square centimeter to joules per square meter, multiply by 10.

Example: 10 mJ/cm² × 10 = 100 J/m².

In the other direction, 1 J/m² = 0.1 mJ/cm².
