Millibars, or mb for short, and kilopascals, abbreviated kPa, measure pressure. The millibar is commonly used in weather reports by meteorologists. Kilopascals are a unit of pressure in the metric system. Each kilopascal equals 10 mb. You might need to convert the pressure in millibars to kilopascals if you have a weather reading but need to convert it to a metric unit or if you want to compare a pressure reading in millibars to other pressure readings in kilopascals.

1
Multiply the number of millibars by 0.1 to convert to kilopascals. For example, if you have 93 millibars, multiply 93 by 0.1 to get 9.3 kPa.
-
2
Divide the number of millibars by 10 to convert to kilopascals. In this example, divide 93 by 10 to verify your answer of 9.3 kPa.
