Thank you for sharing! I'm currently taking a pharmacy tech class and have been struggling to understand how to find different concentrations. I get it now! I'll be sharing this video with other people in my class!

Hello, Thank you for the time you are takeing to make these videos. I'm at a online school and the books are ok but they don't cover everything as clean and precise as you have. A real god send :)

THANK YOU! I couldn't find anything online to help me with these problems.

[christinahowell]

I'll definitely have to let the new calculations class know about your videos!

Hi Charles,
Sometimes conversion can be confusing. If you remember these basic concepts, maybe it will help.1) when you convert units you are never changing the actual amount, you are only renaming it. If you convert 1 dollar to 100 cents, you have the same amount of money, you just renamed it. 2) Set your problem by writing down the units of the answer on the right side of the equal sign. Write down what will be converted on the left side, then multiple it by (see part 2)

Hello! this is great! My only concern is the writting is super small, and I cant make it out but I was able to follow along by listening, great video thank you! Wish me luck on my test!!

Thank you! Im studying this very thing right now in my Pharmacy Technician online course and SEEING it done in front of me (well on the video) is helpful since Im unable to go through the same course in a physical classroom setting. Math is a really tough subject for me.

Hi Stacy,
Thanks for the nice comment. I know some of the pharmacy math books out there are confusing, that is why I ended up writing my own book. You can download it on the main page along with some exercises. Let me know if you have any questions.

I thought I had seen all your videos. thank you so much for sharing your knowledge with us,

[chrisharris]

Hey Doc, can you make a video that addresses this video's concept please? This series is called the PTCB review... I had to send the link via e-mail.

[BradWojcikPharmD]

Also, I think it would be helpful if you download the handout book from the main page.

Thank You So Much.. This video is really helpful.. Its easy for me to picture out the problem this way and apply it in real setting. It does make sense. Now I realize that its important to go back to the basics.. What is Ask? What is given? kind of stuff. :)

Thank you! My dream is to have as many views as some of those crazy cat videos.

a conversion factor so that the units given (what you are converting) are canceled out and you are left with the units of the answer. Remember, all conversion factors always = 1.
2 g (1000 mg/1 g) = 2000 mg. The g on top and bottom cancel each other out. You are left with mg in the answer. 1000mg/1g = 1
