Torr to Millibar Converter

Pressure · unit-converter

Convert Torr to Millibar with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through pascal with fixed definitions (standard atmosphere = 101,325 Pa; torr and mmHg = atm/760; plus industrial/manometer units like kgf/cm², inHg, inH2O, and mmH2O).

About Torr

The torr is defined as 1/760 of a standard atmosphere (≈133.32236842105263 Pa). It is widely used in vacuum science alongside pascal.

About Millibar

Millibar (mbar) equals 100 Pa and is numerically identical to hPa. It appears in weather and legacy instrument labels.

How to convert torr to millibar (mbar)

1 torr equals 1.3332236842105263 millibar in this tool (via pascal):

1 torr = (133.32236842105263 Pa ÷ 100 Pa) mbar = 1.3332236842105263 mbar

Each torr carries 133.32236842105263 Pa and each millibar 100 Pa, so one torr equals 133.32236842105263 ÷ 100 mbar.

Let p(torr) be pressure in Torr (torr), and p(mbar) in Millibar (mbar). Then:

p(mbar) = p(torr) × (133.32236842105263 / 100)

Equivalently, divide by how many torr fit into one mbar (Pa per mbar divided by Pa per torr):

p(mbar) = p(torr) ÷ 0.7500616827041697

Examples

Example #1: Convert 1 torr to millibar

1 torr = 1 torr × (133.32236842105263/100) mbar = 1.3332236842 mbar

1 torr = 1 torr ÷ 0.7500616827041697 = 1.3332236842 mbar

1 torr × (133.32236842105263/100) = 1.333224 mbar

Example #2: Convert 10 torr to millibar

10 torr = 10 torr × (133.32236842105263/100) mbar = 13.3322368421 mbar

10 torr = 10 torr ÷ 0.7500616827041697 = 13.3322368421 mbar

10 torr × (133.32236842105263/100) = 13.332237 mbar

Summary

To convert Torr to Millibar, multiply the value in torr by (133.32236842105263 Pa per torr) / (100 Pa per mbar). Equivalently: value_mbar = value_torr × (133.32236842105263 / 100). Numerically, 1 torr equals 1.3332236842105263 mbar.

Relationship context

Both Torr and Millibar are converted by fixed multiples of the pascal. Multiplying by (Pa per torr) ÷ (Pa per mbar) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
