Millibar to inHg Converter
Pressure · unit-converter
Convert Millibar to inHg 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 Millibar
Millibar (mbar) equals 100 Pa and is numerically identical to hPa. It appears in weather and legacy instrument labels.
About inHg
Inches of mercury (inHg) is used in aviation altimetry and vacuum readings in some US contexts.
How to convert millibar (mbar) to inch of mercury (inhg)
1 millibar equals 0.029529987508079485 inhg in this tool (via pascal):
1 mbar = (100 Pa ÷ 3386.38815789 Pa) inhg = 0.029529987508079485 inhg
Each millibar carries 100 Pa and each inhg 3386.38815789 Pa, so one mbar equals 100 ÷ 3386.38815789 inhg.
Let p(mbar) be pressure in Millibar (mbar), and p(inhg) in inHg (inhg). Then:
p(inhg) = p(mbar) × (100 / 3386.38815789)
Equivalently, divide by how many mbar fit into one inhg (Pa per inhg divided by Pa per mbar):
p(inhg) = p(mbar) ÷ 33.8638815789
Examples
Example #1: Convert 1 mbar to inhg
1 mbar = 1 mbar × (100/3386.38815789) inhg = 0.0295299875 inhg
1 mbar = 1 mbar ÷ 33.8638815789 = 0.0295299875 inhg
1 mbar × (100/3,386.38815789) = 0.029530 inhg
Example #2: Convert 10 mbar to inhg
10 mbar = 10 mbar × (100/3386.38815789) inhg = 0.2952998751 inhg
10 mbar = 10 mbar ÷ 33.8638815789 = 0.2952998751 inhg
10 mbar × (100/3,386.38815789) = 0.295300 inhg
Summary
To convert Millibar to inHg, multiply the value in mbar by (100 Pa per mbar) / (3386.38815789 Pa per inhg). Equivalently: value_inhg = value_mbar × (100 / 3386.38815789). Numerically, 1 mbar equals 0.029529987508079485 inhg.
Relationship context
Both Millibar and inHg are converted by fixed multiples of the pascal. Multiplying by (Pa per mbar) ÷ (Pa per inhg) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
