Joules per square centimeter to joules per square meter
Type a value in J/cm² to get it in J/m² instantly.
100,000J/m²
That's about the same as a laser hair-removal pulse.
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/cm² to J/m²
To convert joules per square centimeter to joules per square meter, multiply by 10,000.
Example: 10 J/cm² × 10,000 = 100,000 J/m².
In the other direction, 1 J/m² = 0.0001 J/cm².
