Turn a dose into a line on the syringe.
Milligrams, micrograms, millilitres, units. Any one to the others.
What you need
One number. Your strength.
Before you start.
- This tool converts any one of milligrams, micrograms, millilitres and syringe units into the other three.
- Have the protocol sheet from the quiz for the vial size and the water, which together set the strength of your mix.
- You get all four figures at once, and the syringe drawn at the result.
Step 01 of 5
What size is your vial?
It is printed on the label, in mg. Together with the water it sets the strength.
- U-100, 1 mlThe standard. One hundred units in a millilitre, labelled every ten.
- U-100, 0.5 mlSame scale, half the barrel. Fifty units, labelled every five, with finer marks for small draws.
- U-100, 0.3 mlSame scale, the shortest barrel. Thirty units, for draws under a third of a millilitre.
- U-40, 1 mlA different scale. Forty units in a millilitre, so the same volume reads fewer units than on a U-100.
What to do with the number.
Read the units figure and draw to that line. If your sheet gives a dose in micrograms and you were thinking in milligrams, this is where the two meet.
The syringe scale matters. If yours is a U-40, choose it here; the same volume reads fewer units on it.
Try it with an example.
Watch the four fields move together: a 10 mg vial in 2 ml, and 250 mcg typed into the micrograms field.
Why the same dose reads differently.
A dose is an amount of peptide, in milligrams or micrograms. A syringe measures volume, in millilitres, and prints that volume as units. The conversion between the two is the strength you mixed, and only that: more water makes the same dose a larger draw, less water a smaller one. The syringe scale then decides the number on the barrel. Every U-100 syringe, whatever its length, reads 100 units in a millilitre. A U-40 reads 40.
So a 250 microgram dose from a 10 milligram vial mixed with 2 millilitres is 0.05 millilitres, which is 5 units on any U-100 syringe and 2 units on a U-40. The dose has not changed; the number has. Take the number from this tool and the strength you actually mixed, and the line on your sheet and the line on the syringe agree.
Questions
Why does the same dose give a different number of units for my friend?
Because they mixed a different amount of water. The dose is the peptide; the units are the volume it sits in. Different water, different strength, different line on the syringe, same dose.
Which field should I type in?
Whichever number you have. If the sheet says 250 mcg, type in micrograms. If you already know you drew 0.1 ml, type in millilitres. The other three update as you type.
What is the difference between mg and mcg?
A thousand. One milligram is a thousand micrograms. It is the single easiest place to make a large mistake, which is why this tool shows both at the same time.
Where do I find my dose?
On the protocol sheet from the quiz. If you do not have a sheet yet, the quiz makes one in three minutes. This tool converts the dose you give it; it does not choose one.
Which syringe do I have?
Almost always the 1 ml insulin syringe marked to 100 units, which is the U-100. The shorter 0.5 ml and 0.3 ml syringes are the same scale with finer marks. A U-40 is a different scale and is rare here.
