PSI ↔ ATM Converter

Convert between Pounds per Square Inch (PSI) and Atmosphere (ATM) instantly

Pounds per Square Inch (PSI)

Enter PSI value to convert to ATM

Atmosphere (ATM)

Enter ATM value to convert to PSI

Conversion Result

14.696 PSI = 1 ATM

1 atmosphere = Standard atmospheric pressure at sea level

📚 PSI ↔ ATM Conversion Details

PSI to ATM Formula

ATM = PSI ÷ 14.6959488

To convert PSI to ATM, divide the PSI value by 14.6959488.

ATM to PSI Formula

PSI = ATM × 14.6959488

To convert ATM to PSI, multiply the ATM value by 14.6959488.

Bidirectional Conversion

This converter works both ways simultaneously:

Type in PSI → ATM updates automatically
Type in ATM → PSI updates automatically
No buttons to click - works as you type

Common Uses

Scuba diving tank pressure
Tire pressure monitoring
Industrial pressure systems
Scientific experiments

📏 How This Converter Works

This is a bidirectional converter that works in real-time:

PSI → ATM: When you type in the PSI field, the ATM field automatically updates
ATM → PSI: When you type in the ATM field, the PSI field automatically updates
No swapping needed: Both conversions happen simultaneously
Real-time: Updates happen as you type, no button clicks required

// Conversion factor
const PSI_TO_ATM = 1 / 14.6959488;
const ATM_TO_PSI = 14.6959488;

// PSI to ATM
ATM = PSI × PSI_TO_ATM

// ATM to PSI
PSI = ATM × ATM_TO_PSI

// Example: Convert 29.392 PSI to ATM
ATM = 29.392 × (1/14.6959488) = 2

❓ Frequently Asked Questions

Q: What is the exact conversion factor?

A: 1 ATM = 14.6959488 PSI exactly. This is the standard atmospheric pressure at sea level.

Q: Why is 14.696 PSI commonly used instead of 14.6959488?

A: 14.696 is a rounded value that's easier to remember and use for most practical applications.

Q: How does the bidirectional conversion work?

A: Both input fields work simultaneously. When you change the PSI value, ATM updates automatically. When you change the ATM value, PSI updates automatically.

Q: Do I need to click any button to convert?

A: No! The conversion happens automatically as you type in either field.

Q: How accurate is this converter?

A: This converter uses the exact conversion factor (14.6959488) and provides calculations up to 6 decimal places.
