Torr to atm Converter
Use our torr to atm converter to convert pressure from torr to atmosphere (atm) instantly. Learn how to convert torr to atm using the torr to atm conversion formula, plus the reverse atm to torr formula and examples.
What is Torr to Atm Conversion?
Torr and atmosphere (atm) are both pressure units. Torr is commonly used in vacuum and lab settings, while atm is a standard reference unit for pressure at sea level.
If you’re wondering are torr and atm the same (or is torr equal to atm), the answer is no. They measure the same thing (pressure), but 1 atm is much larger than 1 torr.
This page covers conversion between torr and atm in both directions: torr to atm and the reverse atm to torr conversion calculator-style formula.
Torr to Atm Formula
The torr to atm conversion is based on the standard relationship that 1 atm = 760 torr. To convert torr to atmosphere (atm), divide by 760. To convert atm to torr, multiply by 760.
This is the torr to atm conversion formula. Example: 1 torr to atm pressure = 1 ÷ 760 atm.
This is the atm to torr formula. Use it for an atm to torr conversion calculator-style conversion.
So 1 torr to atm is approximately 0.0013158 atm.
If you’re asking how many torr in 1 atm (or how much torr in atm), the standard answer is 760 torr per 1 atm.
How to Convert Torr to Atm
- 1
Enter the pressure value in torr.
- 2
Divide the torr value by 760.
- 3
Read the result in atm (atmosphere).
- 4
If you need atm to torr instead, multiply atm by 760 using the reverse formula.
Frequently Asked Questions
No. Torr and atm are both pressure units, but they are not equal. The standard relationship is 1 atm = 760 torr.
Use the torr to atm conversion formula: atm = torr ÷ 760.
Divide torr by 760 to get atm: atm = torr ÷ 760.
There are 760 torr in 1 atm.
Use the reverse conversion: torr = atm × 760.
No. Torr is smaller than atm. For example, 1 torr to atmosphere conversion is 1/760 atm.
A quick method is to remember 760 torr = 1 atm. For most values, dividing by 760 gives you the atm equivalent.
