mmHg to Bar Converter
Pressure · unit-converter
Convert mmHg 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 mmHg
Millimeters of mercury (mmHg) is common in medicine (e.g. blood pressure). Here it uses the same Pa per unit as torr (133.32236842105263 Pa).
About Bar
The bar is 100,000 Pa. It is convenient for industrial and approximate atmospheric pressures (1 bar ≈ 1 atm).
How to convert millimeter of mercury (mmhg) to bar
1 mmhg equals 0.0013332236842105263 bar in this tool (via pascal):
1 mmhg = (133.32236842105263 Pa ÷ 100000 Pa) bar = 0.0013332236842105263 bar
Each mmhg carries 133.32236842105263 Pa and each bar 100000 Pa, so one mmhg equals 133.32236842105263 ÷ 100000 bar.
Let p(mmhg) be pressure in mmHg (mmhg), and p(bar) in Bar (bar). Then:
p(bar) = p(mmhg) × (133.32236842105263 / 100000)
Equivalently, divide by how many mmhg fit into one bar (Pa per bar divided by Pa per mmhg):
p(bar) = p(mmhg) ÷ 750.0616827041698
Examples
Example #1: Convert 1 mmhg to bar
1 mmhg = 1 mmhg × (133.32236842105263/100000) bar = 0.0013332237 bar
1 mmhg = 1 mmhg ÷ 750.0616827041698 = 0.0013332237 bar
1 mmhg × (133.32236842105263/100,000) = 0.001333 bar
Example #2: Convert 10 mmhg to bar
10 mmhg = 10 mmhg × (133.32236842105263/100000) bar = 0.0133322368 bar
10 mmhg = 10 mmhg ÷ 750.0616827041698 = 0.0133322368 bar
10 mmhg × (133.32236842105263/100,000) = 0.013332 bar
Summary
To convert mmHg to Bar, multiply the value in mmhg by (133.32236842105263 Pa per mmhg) / (100000 Pa per bar). Equivalently: value_bar = value_mmhg × (133.32236842105263 / 100000). Numerically, 1 mmhg equals 0.0013332236842105263 bar.
Relationship context
Both mmHg and Bar are converted by fixed multiples of the pascal. Multiplying by (Pa per mmhg) ÷ (Pa per bar) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
