How much is 1 bar equal to in psi?

The correct conversion from bar to psi shows that 1 bar is equal to approximately 14.5 psi. This is a fundamental conversion in pressure measurements.

Understanding this conversion is useful in various applications, such as machinery operations and system calibrations, where precise pressure readings are critical. In the context of this question, recognizing that 1 bar corresponds to about 14.5 psi illustrates a key relationship between metric and imperial units used in millwright work and engineering.

In contrast, the other options do not accurately represent the relationship between bar and psi. Keeping these conversion factors in mind allows for better understanding and communication when working with different pressure units in real-world applications.
