Calculating the dose - mg versus mL

[Defkid]

how the F do I work out mg to mils? im taking half a mill whats that equal in mg? sorry to sound so novice but f*ck it gotta learn these things..

MOD EDIT: Split into a new topic, because it's a common question and applies to more than just Ostarine.

mils(ml) is measurement of liquid.there is no conversion of ml to mg.how many gm or mg of the compound or powder is in the solution should be on the packaging

First you need to know what the product's concentration is.

I've got no idea, but let's say it's 100mg/mL.

That means you've got 100mg of powder per millilitre of solution. Or to say it another way, 1 millilitre of solution has 100mg of powder in it.

Therefore, half that solution will have half the amount of powder.

0.5mL = 50mg of powder

If you have 1.7mL of solution, you'll have 170mg of powder.

If you have 0.234mL of solution, you'll have 23.4mg of powder .

Still with me?

It's reasonably straight-forward when it's an easy number like 100mg/mL. But if you have something nastier like 170mg/mL, it can be a bit of a bastard. There's a trick to this, but before I type it up... are you ok with simple algebra?

Type it up please Pseu! :pray:

Always confuse my self when it comes to these 'simple' measurements :roll:

OK, this was taught to me by my physics teacher at high school. But it works with any "per" measurement - whether it's "kilometres per hour" or "milligrams per millilitre". (Although if your dosing calculations involve km/hr, you're probably doing something wrong!)

Step 1:

Take your measurement and look at it as an algebraic equation. So 170mg/mL becomes:

170mg = mL

Remember, that means that 170mg of powder is 1mL of solution. Or we could say that there are 170x 1mg-sized lumps of powder in 1ml of solution.

Step 2:

But we want to get 1mg of powder by itself, and see how much solution that will be. So we divide the whole equation (both sides) by 170:

  170mg       mL
  ------  =  ----
    170       170

Step 3:

The 170 top and bottom on the left side cancel each other out:

        mL
mg  =  ----
       170

So 1mg of product = 1/170 mL of solution.

Step 4:

This is the final step. Chances are you're going to want more than 1mg of whatever this product is. Let's say you want 23mg. You've just worked out how much solution is required for 1mg. All you have to do now is multiply both sides by the amount you want - in this case, 23mg:

         23mL     23
23mg  =  ----  =  --- mL  =  0.135mL
         170      170

It's a long-winded way of telling you what to do, but hopefully that explains why as well! :grin:

Brings me back to year 13 Calculus! :clubbed:

[Defkid]

Pseuo Thanks heaps for that man! Im sure most dudes are :roll: at a question like that, but It's another thing that is now embedded in the brain..simple as

[Sifo-Dyas]

Holly crap Pseudo....I have been anally working out intricate doses of gear for years and one look at you calculations and now I am so confused I have forgotten how I do it lol :doh:

[Pseudonym]

Hahah, sorry! I did chemistry, physics, calculus, and statistics in 7th form. Yes... I was that nerd.

So seeing it as an equation makes perfect sense to me, but if you've got an easier way, tell us how you do it.

Is this better?

Alternative method:

If you want 23mg of a 170mg/mL solution, simply calculate 23 ÷ 170 = 0.135mL.

I could have just given you that method in the first place, but it doesn't tell you why it works, and my inner nerd felt compelled to try and teach. (Besides, I can never remember which gets divided by what, so I always end up working it out the long way anyway!)

I thought this was the obvious method. I've always worked it out like that but never thought of all that other stuff :pfft:

[Pseudonym]

wow strong brain is strong.

Nah, I was just crap at writing essays, so I chose subjects that didn't have any, and learnt how to make simple maths look complicated instead. :pfft:

YEAH BUDDY! change the chem to economics and you have me, go go nerd power

Still kind of shocked at how OP doesn't know how much mg his dbol has per ml (you could be taking too much or too little ?)
