Millitorr to millibar

Type a value in mTorr to get it in mbar instantly.

1.333×10⁻⁹mbar

That's 1.33× as empty as ultra-high vacuum, while high vacuum is 750× higher. That is about 1.316×10⁻¹⁰% of atmospheric pressure still in there.

What it means

How empty is it?

Molecule counts and mean free paths are for air at 20 °C. A gauge reading also depends on which gas it was calibrated for.

The math

How to convert mTorr to mbar

To convert millitorr to millibar, multiply by 0.00133322.

Example: 1×10⁻⁶ mTorr × 0.00133322 = 1.333×10⁻⁹ mbar.

In the other direction, 1 mbar = 750.062 mTorr.
