I'm so glad I found this. I'm currently taking my PTU's in New York, and the courses offer such horrible explanations. Now that I found this, it's more comprehensive and understandable. Thank you,THANK YOU!!!
Thanks uploading video, the point system to convert units is really horrible even I have baffling problems in conversion. Thanks to Dr . Brad teaching in a very simple methods.
I like the slower way of teaching, it is helpful. Please assist further by showing a completeness in some of the mathematical conversions in other you tubes.
Oh goodness I should've looked on TH-cam ages ago. Your videos have helped me so much. Thank you thank you! Where is the download that you mentioned in previous comments? I'd love to practice!
Hi Brittney. Glad they helped you. If you go to the main page by clicking on my picture they are under recent posts. Here is the link to the handout book. dl.dropboxusercontent.com/u/47515062/Pharm%20120%20Handouts%20Book%20third%20ed%20Jan%202013nh.docx
You explain it a heck of a lot better than my textbook. I have a learning disability and this helped me understand what I was doing wrong. The only problem that I am having now is converting between this system and the apothecary system.
Hi MinishGirl. I am happy that I could help you. Converting between the apothecary system and metric system is done the same way as all the other conversions, you just need the right conversation factor (ratio). For example, there are about 65 mg/grain, so to convert gr (grains) to mg, you would set the problem up like this. 5 gr (65 mg/gr) = 325 mg. email me at brad.wojcik@gmail.com if you have any questions. Also, I can send you some study material.
Sorry that it took so long to get back to you. I would love some study material. Thank you! I think that the reason why math is giving me such a hard time is because I have a short-term memory impairment, so it makes it hard for me to remember how to set up a problem. How do I request study material?
I’m learning pharmacy tech. I desire to be a pharmacy tech . I truly appreciate this video. Thank you so much. I’ve been struggling with metric system.
You can download my book, Pharmacy Calculations for Pharmacy Technicians: Solving Pharmacy Calculation Problems Without All the Silly Formulas, for free at payhip.com/b/5xVY. It goes into more detail than possible on the videos and is full of practice problems and answers.
This is the basics I pretty much already understand, my problem is that division can sometimes be introduced into the problems and I don't understand how.
Hi Cipher. in these unit conversions you are always multiplying by a conversion factor. The conversion factor will have a numerator and denominator. To change 5000 mg to g you multiply 5000 mg by the conversion factor (1 g/1000 mg). The conversion factors always equal 1. 1 g/1000 mg = 1. I think your confusion probably comes from someone telling you "to change mg to g, divide by 1000". What you are actually doing is multiplying 5000 mg by (1 g/ 1000 mg). If you divided 5000 mg by 1000, you would have 5 mg, not 5 g. Hope this helps. If you have more questions, just email me at brad.wojcik@gmail.com. -Brad
Well, you are multiplying by the conversation factor, but there is division within the conversion factor. In the above example you would be multiplying by 1 g and dividing by 1000 mg. The units of mg cancel out and you are left with the units of g in the answer.

Hey Dr. Brad, thanks so much for the video tutorials because I wouldn't have passed the PTCE yesterday without them!
Congratulations! So glad I could help.
Thanks for this vid. I’m seriously considering pharmacy tech work, and this helps a lot. Thumbs up, and added to favorites.
Glad that you found it helpful.
Thank you Sir. Dr. Brad Wojcik tells problem in very simple way.I do not have the words to explain his Gratitude.
Glad I could help!
Thanks Igan!
thank you! much simpler than the text book wanted
Nicole Duke Glad I could help!

I have a pharmacy technician interview tommorow and this has really helped. I'm not naturally good at maths so thankyou
+Focusandpoetry Glad I could help!
you just made my life so much easier thank you so much
Hi Keshia. Glad I could help. Once you realize that you are just multiplying by different forms of 1, it is much easier.
Oh goodness I should've looked on TH-cam ages ago. Your videos have helped me so much. Thank you thank you! Where is the download that you mentioned in previous comments? I'd love to practice!

thanks so much for sharing the chart system. Some other you tubes are confusing.
Great video! Thanks

MinishGirl Hi Minish Girl. Just sent me an email at Brad.wojcik@gmail.com and I will send you the information.
Very very nice dr.Brad;)

Glad it helped you. Let me know if you have any questions.
this was sooo helpful, thanks so much!
Hi Passiion,
Glad I could help. This is the foundation for most of the problems you will be doing in pharmacy math.
Dr. Brad
This def gave me more confidence in becoming certified. Thanks again Dr. Brad!
thanks helped me alot befour class my teacher made it confusing!
Thanks so much Dr. Brad
You are welcome!
I sent u a message

Brad Wojcik ... Really? Thanks, if there is really no division this will make things a lot easier for me.

This makes me wonder if the college is teaching us right because I’m a new student and I’ve already been told to do what your saying not to do
Hi Trisha. If you want to send me an email at brad.wojcik@gmail.com with the example I can explain it so you can explain it to your instructor.
