15mg in 3ml is 5mg/ml

10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100

sanity check on a volume a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with, that is what the scale said

weighed it, so 15mg in 1.5ml is 10mg/ml, so 1.5mg is 15 units. the vial and the mark line up

the rule i use: 100 divided by the concentration in mg/ml gives you units per mg. at 10mg/ml that is 10 units per mg, at 2.5mg/ml anyway

for the newer people why do some people go by weight and some by volume for the diluent

30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right

normal
