Why is 1 atm defined as exactly 101,325 Pa?

1 atm is defined as exactly 101,325 pascals to provide a standardized reference equal to the average atmospheric pressure at sea level, facilitating consistent scientific measurements.

Can this converter be used for underwater pressure calculations?

Yes, it can convert pressure values related to ambient and depth conditions in diving and underwater engineering by converting atmospheric pressures.

Does this tool account for variations in atmospheric pressure due to altitude?

No, the conversion assumes standard sea-level atmospheric conditions and does not adjust for local or altitude-dependent pressure differences.
