No, there is a difference in density but you are dealing with volume. 1 ml of pg occupies the same amount of space as 1 ml of VG as 1 ml of any liquid occupies the same space. The density is what is different. If trying to be perfectly exact drops can be different sizes. You should really get syringes. I use 10 ml, 3 ml and a 1 ml syringe to reduce any variations from one juice to another being the same recipe. The other variable is that PG holds the flavor more so using more VG you may need to add more flavoring to get the same taste.
If you're doing the 100 drop tester method, I'd just stay one for one. A slightly weak recipe will tell you a lot more than an overflavored recipe.
Look at using a glass dropper, like that of a 30ml bottle, if you're working with VG. The little 3ml pipettes you get from places like TFA don't suck up VG real well, and a fair proportion of syringes don't have a smooth enough action to reliably squeeze drops without squirting a heap out and ruining the test.
Agreed. Just buy some cheap syringes so you can get exact measurements, either thatvor switch to weight based measurement...
Weight based measurement works really well. I mix 5ml test samples when playing with a new or modified recipe. My scale weights to 100th of a gram.
Im lucky, I still have an incubator, magnetic stirrer, hot plate, graduated cylinders, flasks, and a .0001 scale from my chemistry days in college 
Getting into DIY only cost me about 50$

A magnetic stirrer and some glass flasks were the best diy investment i have made,right next to the scale.Those 3 items made a huge difference.
All the answers about using a different measuring method miss the OP's point.
They were asking about doing the 100 drop recipe test method, not looking for advice on what measuring method to use.
As has been discussed in the TFA/TPA mega-thread, just use drops -- one per percent for all ingredients-- and you will be close enough for a flavor test.
Yes you will achieve a slightly different outcome when making your final mix but for flavor test purposes it's close enough and will accomplish your goals.

I do not have hot plate, graduated cylinders, flasks and scale. However my DIY accessories cost me just about $10. May be less, I just do not remember. 3 syringes. It's enough for me to do everything I need to do.

To OP: you sure can use drop method. It is as good as any other if you do not mind to spend considerable time measuring components for 50 ml bottle (or bigger one...)
P.S. I still use drop method to measure flavors. Happens so that I just have most of my flavor in eye-dropper bottles (and I like it).
