Samantha NicoleConverting 109 torr to atm gives approximately 0.1431 atm.
Since 1 atm equals 760 torr, dividing 109 by 760 yields the atm value. This conversion allows expressing pressure from torr into atm, standard units used worldwide for pressure measurements, especially in science and weather contexts.

Conversion Formula
The formula to convert torr to atm is: atm = torr / 760. This multiplication works because 1 atmosphere equals 760 torr. By dividing the number of torr by 760, we get the pressure in atm. For example, 380 torr divided by 760 gives 0.5 atm, showing the pressure is half an atmosphere.
Conversion Example
- Convert 200 torr to atm:
- Step 1: Write the formula: atm = torr / 760.
- Step 2: Substitute: atm = 200 / 760.
- Step 3: Calculate: 200 ÷ 760 ≈ 0.2632 atm.
- Result: 200 torr equals about 0.2632 atm.
- Convert 500 torr to atm:
- Step 1: Use the formula: atm = 500 / 760.
- Step 2: Calculate: 500 ÷ 760 ≈ 0.6579 atm.
- Result: 500 torr is roughly 0.6579 atm.
- Convert 134 torr to atm:
- Step 1: Apply the formula: atm = 134 / 760.
- Step 2: Perform division: 134 ÷ 760 ≈ 0.1763 atm.
- Result: 134 torr is about 0.1763 atm.

Conversion Definitions
torr
The torr is a pressure unit based on the pressure exerted by a millimeter of mercury at 0°C, equal to 1/760 of an atmosphere, used mainly in vacuum systems and scientific measurements.
atm
An atmosphere (atm) measures pressure, defined as the average pressure exerted by Earth’s atmosphere at sea level, equivalent to 760 torr, and used globally in scientific, industrial, and weather measurement contexts.
Conversion FAQs
What is the most common pressure unit used in scientific experiments?
The atmosphere (atm) is widely used in scientific labs for standard pressure measurements because of its relation to Earth’s atmospheric pressure, making it a convenient reference point for experiments involving gases.
Why is the conversion factor between torr and atm exactly 760?
This is because 1 atm is exactly defined as the pressure exerted by a 760 mm column of mercury at 0°C, making 760 torr the precise equivalent of 1 atm, establishing a straightforward division for conversion.
Can I convert any pressure value from torr to atm manually?
Yes, by dividing the pressure value in torr by 760, you can convert it to atm, as the relationship is linear and simple, suitable for calculator or mental calculation when needed.
Is there any difference in using torr or atm in pressure measurements?
Both units measure pressure but are used in different contexts: torr is common in vacuum systems and scientific measurements, while atm is standard in weather, physics, and chemistry, often making conversions necessary for clarity.
