Square meters per gram to equivalent particle size
Type a value in m²/g to get it in µm instantly.
That's 4× as fine as a catalyst support, while activated carbon is 1.2× higher. A five-gram spoonful would cover about 19.16 tennis courts.
Convert the other way: µm to m²/g
What it means
How much surface is that?
Particle sizes assume smooth spheres at 2.5 g/cm³. Real porous materials have far more area than their outside size suggests, which is the point of measuring.
The math
How to convert m²/g to µm
For smooth spheres, area and size are reciprocals: m²/g = 6 ÷ (density × diameter), taking the density as 2.5 g/cm³. Porous materials have far more area than that.
Example: 1,000 m²/g = 0.0024 µm.
