Mean Kinetic Temperature (MKT) is a simplified way of expressing the overall effect of temperature fluctuations during storage or shipment of perishable goods. Consider the following example: EXAMPLE: A dozen eggs sat: In a 20°C room for 2 hours In a 2°C refrigerator for 4 hours And on a 25°C loading dock for 1 hour Using MKT we can calculate that the temperature profile of the eggs was “thermally equivalent” to storing them at 10.096°C for 7 hours. How is Mean Kinetic Temperature Calculated? Technically speaking, MKT is an expression of cumulative thermal stress experienced by a product at varying temperatures during storage and distribution. In other words, MKT is a calculated, single temperature that is analogous to the effects of temperature variations over a period of time. MKT is not a simple weighted average. The calculation of MKT gives the higher temperatures a greater weight when computing the average than would a simple numerical average or an arithmetic mean. This weighting is determined by a geometric transformation— the natural logarithm of the absolute temperature. The International Conference on Harmonization (ICH) stability testing guidelines define MKT as ‘a single derived temperature which, if maintained over a defined period, would afford the same thermal challenge to a pharmaceutical product as would have been experienced over a range of both higher and lower temperatures for an equivalent defined period’. By using this unequal weighting pf the higher temperatures in a temperature series, MKT takes into consideration the accelerated rate of thermal degradation of materials at these higher temperatures. Mean kinetic temperature is a. Systems are capable of recording multiple temperature readings over a time period and some offer the function of calculating. Account the Arrhenius equation.

Mean Kinetic Temperature FormulaTherefore, MKT provides for the non-linear effect of temperature. I presume you are dealing with medicines or other temperature sensitive products and have you wondered at some point about the calculation of MKT? What is Mean Kinetic Temperature in basic language? If you have a set of temperature readings across a certain period of time, the Mean Kinetic Temperature across this period means effective average thermal value for this period. This temperature value is what the stored goods effectively feel during the mentioned time. This is not the arithmetical average of the readings. Mean Kinetic Temperature is calculated for understanding effects of variations in temperature for temperature-sensitive goods during storage and transportation. A sample from our in the image on the right side indicates the MKT value automatically generated in its report. Nowadays we do not need to calculate MKT manually. You can simply place a and the reports will automatically indicate the MKT value. Have you wondered the difference between Mathematical Average value and Mean Kinetic Value? The calculation is different from the Average value which is the sum total of the values divided by the count of the values. Mean Kinetic value is slightly higher than average value. This is particularly important for storage and transportation of medicine, vaccines etc. Example of application of Mean Kinetic Temperature In layman’s language this is explained below: As an example, Free Excel software for automatic calculation of MKT of multiple data loggers we will consider that a medicine which has to be maintained between 2-8 °C is transported for 10 hours. A is kept inside the box for recording the temperature continuously. At the end of the transportation, the recorded temperature data is downloaded and verified. At this point suppose that the temperature has gone above 8 °C couple of times and below 2°C couple times. As the medicine is always to be kept between 2 and 8°C, you are not sure whether the medicine is acceptable or not since the temperature has gone above 8°C few times or below 2°C few times for different durations. In this case, you can check the MKT value of the 10 hours period and if the MKT value is within 2-8°C, the medicine is still considered to have retained all its properties. Hence MKT for a substance can be defined as the calculated value derived from the complete recording over a specified period of time. If this value is within the permitted values, the substance is still considered to be safe. How to Manually calculate Mean Kinetic Temperature in Excel Sheet? Would you be interested in the simplest way using an Excel sheet? All of you are familiar with Excel and hopefully, this will be the simplest calculation method. You may download the free excel sheet which defines a function namely “MKT”. This function can be used similarly to any other function such as SUM, AVERAGE etc. If you do not want to calculate manually, we encourage you to Manual calculation Step by Step The step by step method of calculating MKT is as below: • Convert °C to Kelvin by adding 273.15 to each reading. • Calculate Delta H/(Gas Constant x Temperature Reading).
