How do my semester units transfer into quarter units?

For example, I’m working on the prerequisites for UC Riversides Undergraduate Business program and it says you need a minimum of 32 units in the following classes…My schools is in the semester system, so If i take 15 semester units of the equivalent coursework of that as UCR, how do my 15 units transfer over as quarter units? For example Financial accounting is 5 semester units at my school, and at UCR its 4 quarter units. Will it count as 5 units x 1.5 =7.5 quarter units, or will it count as the 4 units since that’s what unit hours are at this university?
