One atm. equals 760.0 mm Hg, so there will be a multiplication or division based on the direction of the change.
Converting between atmospheres and kilopascals.
One atm equals 101.325 kPa, so there will be a multiplication or division based on the direction of the change
Converting between millimeters of mercury and kilopascals.
760.0 mmHg equals 101.325 kPa, so both values will be involved. This situation is slighly unusual because most conversions involve a one, usually in the denominator. The conversion examples above are examples of a one being involved. For example, 760.0 mmHg / 1.00 atm in examples 1 and 2. The 1.00 was assumed to be present.
In this conversion, both 760.0 and 101.325 will be involved and the location of each (numerator or denominator) will depend on the conversion.
