Hi

How much does 60ml concentrate at 20% make?


Also could there be a sticky of how many mls make what (saves me asking in future)

[izan]

convert to a fraction and multiply.
20% = 1/5
5*60= 300
300 ml produced from 60ml at 20%.

cheers mate, fractions isn't my strong point lol

I can see 300ml of red astaire being made

[Richard46]

OK no fractions
60 divided by 20 = 3
3 x 100 = 300

Ok I understand the 60 / 20 = 3

But where did the 100 come from to x by 3




Either I'm really stupid or I'm def missing something lol

The 100 is to turn the figure into a percentage mate
Another way of looking at it might be- 60ml at 10% would make 600ml therefore at 20% you could make 300ml

No, because the 60ml of concentrate is 20% of the Total.

300ml is 100%

You cannot have 120%

[fisher]

ok, my math is wrong, but I always thought if you make 100 ml of mix, and it was 80/20 ml then surely that is 25% flavour. I do see what you mean by 20% of the total though

If you can't get your head around percentages or fractions:

Divide 100 by the percentage number (20) which gives 5, then multiply your 60ml by the 5 to get 300ml of liquid.

The 100 came from the %
Per cent = per hundred

Too polite to say what How do you know whether the bar maid has short changed you?

ok maths peeps

2 more questions (one is mega easy) - 2% of flavouring - 50ml bottle of flavouring - how much does that make?

And also 200ml of 70mg/ml nicotine at a ratio in e-liquid of 0.5mg/ml - vaping 30ml a day?

Thanks and happy christmas

1) 1% is 2ml. 100% is 25ml x 100% = 2500ml.
2) 200ml x 70mg = 14000ml. 14000ml / 0.5mg = 28000ml. 28000ml / 30ml = 933 days.



I need more coffee. Thanks to izan for this post.

[izan]

2% is 1/50
50*50ml = 2500 ml from 50ml of flavour mixed at 2%
------------------------------------------------------------------
200ml@70mg/ml makes : 2800ml @5mg/ml. So..about 3 months worth.
