PSI to Atmospheres Pressure Converter

Use this endpoint when you need a quick, single-value PSI-to-atmospheres pressure conversion without setting up your own math. Ideal for engineering, scientific, or industrial workflows where pressure readings in PSI need to be expressed in standard atmospheric units (atm). Prefer this over a general-purpose math API when the specific conversion semantics and labeling matter.

• Missing 'value' query parameter returns an error
• Non-numeric value string causes a conversion failure
• Negative or zero values may return unexpected results depending on validation
