Conversion Formula
Torr = Atmosphere × 760.0021001785
Atmosphere = Torr × 0.0013157858
Factors are from BIPM SI brochure and NIST SP 811, stored unrounded and computed via a base unit. Reverse factor is 1 ÷ 760.0021001785.
How to convert Atmosphere to Torr
Multiply the value in atmosphere by 760.0021001785 to get torr. For example, 5 Atmosphere = 3800.0105008926 Torr. All results in the pressure converter update instantly as you type, so you can see every unit at once without manual math.
Common mistakes
Do not round the factor to 760. too early — keep full precision until the final display. For pressure, always verify critical calculations (medicine, engineering) with a second source.
