I am looking to create a sheet that allows users to enter costs either as monthly or as annual and have the other update.
As soon as they enter data in the monthly cell, I'd like the annual cell to have that value * 12.
As soon as they enter data in the annual cell, I'd like the monthly cell to have that value / 12.
I found an example online of an Ohms Law Calculator that has approximately the behavior I want.
Is this possible? I struggle to find search terms.
