Ml/mg Vial Question

Hey guys,

Quick question. I usually get 200ml/mg vials in which I inject 50ml which equals 100mg.

I just got a 250ml/mg vial. Confused as to the conversion. Can anyone help me out on this?

Thanks

0.4ml x 250mg/ml = 100mg

0.4ml is 40 units on an insulin syringe.

It’s a ratio.

X / 100 = 1 / 250 solve for x.

X = 1 / 250 * 100 = 0.4ml

If you want 150mg, then it’s the same thing:

X / 150 = 1 / 250 solve for x.

X = 1 / 250 * 150 = 0.6ml
