Question: how many nanometers is in a grain of sand?
Asked by garfield is god to Hugh on 7 Nov 2018.
answered on 7 Nov 2018:
Geologists say that a sand particle is between 0.0625 mm to 2 mm.
The mm means millimeter, its probably the smallest unit of length on one of your rulers, it means you take 1 meter and divide it by one thousand (1,000).
A nm means a nanometer, that means you take 1 meter and divide it by one billion (1,000,000,000).
If we convert 0.0625 mm and 2 mm to nanometers we have
62,500 nanometers to 2,000,000 nanometers.
Here’s a great video which explains what a nanometer is!
