Help converting a formula to an equation
Help converting a formula to an equation
(OP)
I'm trying to figure out what the equation would look like in Excel Equation Editor for a particular formula. I can write it in Excel but was never good at rearranging an equation to solve for other variables.
Attached is a short spreadsheet with the information. The formulas use "Named" references and the notations are in column D, with the associated values in Column C.
The solution to the equation I'm trying to write, is in C19 (Ca). The other equation that needs to be rearranged is in the spreadsheet and the solution for that equation is in cell C12 (Qa)

You already have the Excel formula (Ca). So all you need to do is substitute the formulas for S & So. All your other variables are constants.
Skip,
Just traded in my OLD subtlety...
for a NUance!

Raise 10 to the power of the result on both sides.
Divide both sides by 100.
Invert both sides
Subtract 100 from both sides.
Negate both sides.

Why don't you try an add-in called ExcelCalcs (www.excelcalcs.com). This will automatically convert your cell formulas to an equation. No need for the Equation Editor. See attached file.

Function GetFormula(cell)
GetFormula = cell.Formula
End Function
and then type in the cell GetFormula('cell reference')
