| Example of use: To convert millibars to psi, find the 1 under the millibar column. The 1 marks the row that contains multipliers to convert millibars to other units. Follow the row to the psi column. The multiplier is 0.014504. Thus you would mulitiply the millibar value by 0.014504 to convert it to psi. Note that factors related to head of water are derived from water at a temperature of 4 degrees C ( 39.2 degrees F). | |||||||
