Conversion Formula
The formula to convert torr to atm is dividing the number of torr by 760 because by definition, 1 atm equals 760 torr. This works because pressure units are based on a standard pressure measurement, making the conversion straightforward. For example, 380 torr divided by 760 gives 0.5 atm, showing half an atmosphere.
Conversion Example
- Convert 150 torr to atm:
- Step 1: Write down the conversion formula: atm = torr / 760.
- Step 2: Substitute 150 for torr: atm = 150 / 760.
- Step 3: Perform division: 150 / 760 ≈ 0.1974.
- Step 4: Result: 150 torr equals about 0.1974 atm.
- Convert 220 torr to atm:
- Step 1: Use the same formula: atm = 220 / 760.
- Step 2: Calculate: 220 / 760 ≈ 0.2895.
- Step 3: Result: 220 torr is about 0.2895 atm.
- Convert 90 torr to atm:
- Step 1: Apply the formula: atm = 90 / 760.
- Step 2: Calculate: 90 / 760 ≈ 0.1184.
- Step 3: Result: 90 torr equals roughly 0.1184 atm.

Conversion Definitions
torr
The torr is a pressure unit defined as exactly 1/760 of an atmosphere, used mainly in vacuum measurements, named after Evangelista Torricelli. It measures pressure based on the height of a mercury column in barometers, providing a precise pressure standard.
atm
The atmosphere (atm) is a pressure unit that was originally based on Earth’s average sea-level pressure. It equals 760 torr and is widely used in scientific and industrial contexts to describe pressure, standardizing measurements across different systems and experiments.
Conversion FAQs
Why does dividing by 760 convert torr to atm?
This is because the definition of atm is exactly 760 torr. Dividing the value in torr by 760 scales it down to the equivalent pressure in atmospheres, making it a direct conversion based on their fixed relationship.
Can I use this conversion for other pressure units?
No, this specific formula only applies to converting torr to atm. For other units like psi or kPa, different conversion factors are needed, as they are based on different standards and measurements.
What happens if I input a negative pressure in the converter?
Negative pressure values are physically meaningless in this context, but mathematically, the converter will display a negative atm value, which doesn’t represent a real pressure but can be used for theoretical calculations.
Is the conversion accurate for very high pressures?
Yes, as long as the pressure is measured in torr, dividing by 760 remains accurate regardless of the magnitude, since the relationship is linear and based on fixed standards.
