Next we use the вЂњActiveSheet.RangeвЂќ function to select cell вЂњD4вЂќ and set its value based on conversion calculation as a function of вЂњB4вЂќ value.ДЄctiveSheet.Range('D4').Value = (ActiveSheet.Range('B4').Value - 32) * 5 / 9 If Not Intersect(Target, Range('B4')) Is Nothing Then Realization of ITS-90 from 273.15 K through 1234.93 K: Calibration and Accuracy of Secondary Standard PRT's to the ITS-90. The logic here is not too complex and has two parts:Д¬heck that the B4 (or D4) cell was part of the Target change range, for that we check if the intersection between Target and вЂњB4вЂќ is not empty. Click on the Excel document attached below named Calc Res or Temp from ITS90 coeffs. This will generate for you an empty Private Sub called Worksheet_Change. LetвЂ™s review these statements one by one.ДЇirst please open the VBA editor in Excel (see old post about that) and use the drop-down lists to first select вЂњWorksheetвЂќ and then вЂњChangeвЂќ. It also requires the Excel to be saved as. The event will be triggered every time a cell is changed, making this solution a little bit heavy when dealing with large Excel files. The workaround I found is by going down-level to the VBA level and writing a macro to handle a вЂњworksheet changeвЂќ event. It creates bi-directional dependency between two cells that as far as i can tell can not be done with simple expressions. Just type in B4 the expression:Д«ut doing both is much tougher.

Just type in D4 the expression:Дeveloping an expression that can do the reverse (still a one-directional conversion) form Celsius to Fahrenheit is easy. The end result should look like the following:Дeveloping an expression that can do a one-directional conversion form Fahrenheit to Celsius is easy. Changing one of them will need to automatically change the other one. LetвЂ™s assume that Cell B4 represents temperatures in Fahrenheit and Cell D4 represents temperatures in Celsius. Sounds simple enough but the trick here is the bi-directional statement.

I recently received a question on how to develop a bi-directional temperature converter in Excel.
