This is a standardised unit of measurement for the hotness of a female, based on Mila Kunis being a 1, anything hotter being above 1 and anything not as hot being below. Also known as a NKU.
It has been discussed at length and there is no mathematical comparison between the 0-10 scale and the Nominal Kunis Unit scale. Save yourself the time and don't bother, it's mathematical anomaly.
"Emma Stone is a 0.7 NKU"
"Margot Robbie is definitely a 1.1 NKU"
"I disagree I think she is only a 0.9 Normalised Kunis Unit"
Girl A: "OMG last night with Jake was terrible!"
