Info Dosing with calipers updated w/videos

I just brought some calipers. I watched the video. I am not a math person by any means. But there are a couple of things I'm questioning.

1. mm=metric meters
ml=metric liters also (cc) this is how insulin is measured, units per cc.

These are quite different.

2. Is the insulin in the needle (not just the barrel) being accounted for?

Trying to figure this out.
 
mm = milimeters, which is a measure of distance. The calipers are not measuring the amount of insulin in the syringe, but rather how far up on the syringe barrel that you should draw insulin to. Since the lines on many syringes, including my BD's, have the zero line marked inconsistently from syringe to syringe, the caliper arms are a substitute for the unit markings on the barrel.

You don't need to worry about the insulin in the needle, it should be the same no matter where you draw the plunger to.
 
Here is an explanation of the problem of the "cone" in the Monoject syringes. I sketched it several years ago and just today it seems to be relevant again. If the base of the needle doesn't go all the way to the zero line, any insulin in the cone will add to the dose.

For those who have Amazon Prime, they can order the same caliper there that Harbor Freight carries and won't have to pay shipping. So will save a little. :)

Yes...true. We have a Harbor Freight in town so it’s easy. But if you don’t, Amazon is good but you have to have Prime. Not everyone does. In that case, I’d order from HF because, unfortunately, you don’t always know that what you are getting from Amazon is the real deal. I’ve had it happen.

True but I always make sure on sellers and usually only purchase what can be shipped from an Amazon warehouse. Less chance of having a bad experience with an order.

Could someone please explain to me what +0.1 and -0.1 mean in the BD syringes template http://www.diabetes-katzen.net/insulinruler.pdf ?

It has to do with the "thickness" of the plunger tip...you're supposed to measure from the middle, like in the figure on the left....If you look at the figure at the right, if you measure the dose from the "top" of the plunger, it's 0.1 more than the dose you think you measured. If you measure from the "bottom" part of the plunger, it's 0.1 less

If you are not using the BD template but are using calipers, it’s ok to measure from the top of the dosing line as long as you are always consistent.
