The main thing to point about blasting media is that the conversion values are somewhat tricky.

This is because Grit, Mesh, and Micron are based on different values of measurement making an exact mathematical calculation nearly impossible.

However, we’ve come pretty close to the exact grit to micron formula which you can find below.

The formula for Grit to Micron conversion:

What is the formula for grit to microns?

The formula for grit to micron is 11764.71 x grit^(-0.93589) = microns.
Keep in mind, since grit and micron are different units of measurement, an exact conversion is not possible. These values should be within +/- 3%.

How is sandblasting media grit measured?

Sandblasting media grit is measured by how much media passes through or is retained by a series of mesh sieve sizes. The grit size is based on the sieves used.

What is ANSI?

The American National Standards Institute (ANSI) is a private, not-for-profit organization dedicated to supporting the U.S. voluntary standards and conformity assessment system and strengthening its impact, both domestically and internationally.

ANSI sets the standard for particle size distribution and measurement.
