atm to PSI Calculator: Convert Atmospheres to Pounds per Square Inch
Convert atmospheres (atm) to pounds per square inch (PSI) with ease using our atm to PSI calculator. This simple tool helps you quickly determine the equivalent pressure in PSI based on the atm value entered.
Understanding atm to PSI Conversion
Atmospheres (atm) and pounds per square inch (PSI) are both units of pressure, but they belong to different measurement systems. PSI is used in the imperial system, whereas atm is a metric unit commonly used to express atmospheric pressure. Converting between these units is essential for professionals working in various industries, from engineering to meteorology, as it allows for consistent pressure measurements across different systems.
Conversion Factor
The conversion factor between atmospheres (atm) and PSI is that 1 atm is equal to approximately 14.696 PSI.
| Unit | Symbol | Equivalent |
|---|---|---|
| Atmosphere | atm | 1 atm = 14.696 PSI |
| Pounds per Square Inch | PSI | 1 PSI = 0.068046 atm |
Formula for atm to PSI Conversion
The formula to convert atmospheres (atm) to pounds per square inch (PSI) is:
PSI = atm × 14.696
Where:
- atm: Atmospheres
- PSI: Pounds per square inch (the result)
Common Applications of atm to PSI Conversion
| Application | Typical atm Range | Typical PSI Range |
|---|---|---|
| Atmospheric Pressure | 1 atm | 14.7 PSI |
| Vacuum Systems | 0-1 atm | 0-14.7 PSI |
| Car Tires | 2-3 atm | 29.4-44.1 PSI |
Frequently Asked Questions
What is the relationship between atm and PSI?
Atmospheres (atm) is a unit of pressure commonly used for atmospheric pressure measurements, while PSI is a unit used in the imperial system. The relationship between the two is that 1 atm is equal to approximately 14.696 PSI.
How do I convert atm to PSI?
To convert atmospheres (atm) to pounds per square inch (PSI), simply multiply the atm value by 14.696.
Why is atm used instead of PSI in some regions?
Atmosphere (atm) is primarily used in scientific, meteorological, and atmospheric measurements, especially in countries that use the metric system. PSI is used more commonly in industrial and mechanical applications, particularly in countries using the imperial system such as the United States.
Can I use this calculator for barometric pressure measurements?
Yes! This calculator is ideal for converting barometric pressure values, typically measured in atmospheres (atm), into PSI for applications where imperial units are required.
