inHg to Bar Converter
Pressure · unit-converter
Convert inHg to Bar 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 inHg
Inches of mercury (inHg) is used in aviation altimetry and vacuum readings in some US contexts.
About Bar
The bar is 100,000 Pa. It is convenient for industrial and approximate atmospheric pressures (1 bar ≈ 1 atm).
How to convert inch of mercury (inhg) to bar
1 inhg equals 0.0338638815789 bar in this tool (via pascal):
1 inhg = (3386.38815789 Pa ÷ 100000 Pa) bar = 0.0338638815789 bar
Each inhg carries 3386.38815789 Pa and each bar 100000 Pa, so one inhg equals 3386.38815789 ÷ 100000 bar.
Let p(inhg) be pressure in inHg (inhg), and p(bar) in Bar (bar). Then:
p(bar) = p(inhg) × (3386.38815789 / 100000)
Equivalently, divide by how many inhg fit into one bar (Pa per bar divided by Pa per inhg):
p(bar) = p(inhg) ÷ 29.529987508079486
Examples
Example #1: Convert 1 inhg to bar
1 inhg = 1 inhg × (3386.38815789/100000) bar = 0.0338638816 bar
1 inhg = 1 inhg ÷ 29.529987508079486 = 0.0338638816 bar
1 inhg × (3,386.38815789/100,000) = 0.033864 bar
Example #2: Convert 10 inhg to bar
10 inhg = 10 inhg × (3386.38815789/100000) bar = 0.3386388158 bar
10 inhg = 10 inhg ÷ 29.529987508079486 = 0.3386388158 bar
10 inhg × (3,386.38815789/100,000) = 0.338639 bar
Summary
To convert inHg to Bar, multiply the value in inhg by (3386.38815789 Pa per inhg) / (100000 Pa per bar). Equivalently: value_bar = value_inhg × (3386.38815789 / 100000). Numerically, 1 inhg equals 0.0338638815789 bar.
Relationship context
Both inHg and Bar are converted by fixed multiples of the pascal. Multiplying by (Pa per inhg) ÷ (Pa per bar) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
