Square centimeters per second to square millimeters per second
Type a value in cm²/s to get it in mm²/s instantly.
0.001mm²/s
That's 100× as fast as a protein in water, while salt in water is 1.5× faster. In an hour a molecule would wander about 2.683 mm.
What it means
How fast does it spread?
Diffusion distances go with the square root of time: four times as long gets you only twice as far.
The math
How to convert cm²/s to mm²/s
To convert square centimeters per second to square millimeters per second, multiply by 100.
Example: 1×10⁻⁵ cm²/s × 100 = 0.001 mm²/s.
In the other direction, 1 mm²/s = 0.01 cm²/s.
