I don’t know the measurements, but I made a video of me making my favorite cheeze sauce for Vegan Mac and Cheeze with veggies!! 

You can google different recipes and I absolutely LOVE the version I make over all the others I’ve tried! It’s taken a LOT of trial and error to strike the balance we like!!! 
Add a can of Rotel Diced Tomatoes and Green Peppers to make this a vegan version of chili con queso!!! It’s Delish!!!
