Converting Measurement Units: Using the Convert Function in Microsoft Excel
Joshua has work experience in manufacturing, distribution, and aerospace. He received his BBA in accounting from Kent State University.
The Convert Function
The convert function in Excel converts a number from one measurement type to that of another.
Why Use Excel to Convert Measurement Units
Microsoft Excel can play hard ball when it comes to creating conversion tables. The Convert function can be utilized when one has a lot of data to convert to an alternate unit of measurement. The convert function coverts weight and mass, distance, time, pressure, force, energy, power, magnetism, temperature, volume, area, information, speed, prefixes and binary prefixes. With all of these types of conversions it’s safe to say that this is indeed a powerful function of Excel.
Convert Function Example: Fahrenheit to Celsius Coversion
A common conversion is from Fahrenheit to Celsius when measuring temperature. A blank worksheet and completed worksheet for the following example data can be downloaded here. Data is displayed below in Fahrenheit and needs to be converted to Celsius. This can be easily accomplished by using the convert function.
To start using this function type “=convert(“ in the cell where you would like the converted data to display. There are only three pieces of data that the convert function needs to create a conversion. The first of the data is the original unit measurement (in this case Fahrenheit). The original measure can be a value or a cell that contains that value. The next two values need to represent values that tell Excel from what measurement and to what measurement.
For this function to work properly the syntax must be used properly. In the illustration below the cell B4 is being converted from “F” to “C” or from Fahrenheit to Celsius. There should be a comma with no spaces between each set of data in this function. To convert Atlanta's January high to Celsius you would have to type =convert(B4,"F","C")
Once the formula is entered formula can be copied down with the fill handle to convert the rest of the Fahrenheit temperatures in column B.
Correct Syntax Use
The remainder of this text consists of tables for different types of measurements. Take notice to the next table down that displays available syntax for temperature measurements. With a simple change in the function Fahrenheit in the example can also be changed to Degrees Rankine, Degrees Réaumur or Kelvin. Any unit contained in an individual table can be converted to another unit within that table only.
