Enter the time (minutes) and the temperature (C) into the Calculator. The calculator will evaluate the Pasteurisation Units. 

Pasteurisation Units Formula

PU = t *1.393^(T-60)


  • PU is the Pasteurisation Units (units)
  • t is the time (minutes)
  • T is the temperature (C)

To calculate Pasteurisation Units, multiply the time in minutes by 1.393 raised to the power of the temperature minus 60.

How to Calculate Pasteurisation Units?

The following steps outline how to calculate the Pasteurisation Units.

  • First, determine the time (minutes). 
  • Next, determine the temperature (C). 
  • Next, gather the formula from above = PU = t *1.393^(T-60).
  • Finally, calculate the Pasteurisation Units.
  • After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

time (minutes) = 2

temperature (C) = 60
