? Conversion chart questions

Can somebody help me with the conversion chart please. I'm going to have to switch over to my iPad because a lot of things I can't see right now with my cell phone. The last time I looked at the conversion chart it had me using 5 U using U100 syringes when I used 2 units using my U 40 syringes . Is 1.5 U using U40 = 3 U with the U 100 syringes ?
Is this correct?

And I've lost all my data On skittles spreadsheet , all that I can see are a few from 2015. What do y'all see? Do I need to post this question in the tech support section?

 

That is correct. A U40 insulin has 40 units/ml while a U100 has 100 units/ml.
Filling a U100 syringe with U40 insulin to the 2.5 unit markings results in the U100 syringe holding 1 unit of U40 insulin.
2 units of U40 insulin would be to the 5 unit marking on a U100 syringe

 

Hope this helps! The chart is at the bottom. I have a similar one I printed and have it with my syringes.

Thanks y'all . Drawing up 5 units in a U100 seems like so much compared to my U40 syringe
