Help with DAC Calibration

Hello, I'm looking over the document, "Open-Loop Calibration Techniques for Digital-to-Analog Converters" on the web page: https://www.analog.com/en/analog-dialogue/articles/open-loop-calibration-techniques.html.
I understand the calculations up to the end:
Actual DAC input = (10 V/10.05 V) × Ideal DAC input + 196
But I'm stuck at the value of Ideal DAC input.
196 has units of counts, so the Ideal DAC input would be counts or unitless. Or, would it be:
Ideal DAC Input = Scale Factor x (expected Voltage output)
Scale Factor = (2^n -1)/(Full Scale Voltage).
Can anyone help me please.
Thank you
