How do you change percent to grams?

Answer 1

There is no direct corrolation, percent is a measure of something, grams is something you measure.

To be wanting to change percent into grams means you have some sort of instructions telling you to use a percentage(%) of somethings total weight in grams.

For instance "Add sugar equal to 5% of mixtures total weight).

To work out the grams you are asking for, you need to know to total weight in grams first. Then, you work out the percentage you need. The easiest way to do this if you are not great with maths is to split the sum up into manageable chunks. What I liked to do is find away to get my answer by making the sums easier. If we use the above example of 5% sugar, I would normally find out 10% of something than halve it (5 is hald of 10, so whatever 10% of something is, 5% is half of that) .10 is an easy number to use, as you move the decimal point back one space, and that number is 10%.

Example, I have the number 1823, the decimal point comes at the end of the whole number and signifies where the decimal numbers begin (these are numbers that are used when a number is less than 1 but more than 0-half of 1 is shown as 0.5 for example, this is known as a fraction, as it is only a piece of a whole number) when there no fractions, the decimal point is still at the end, but there are no numbers after it. Now then, when we work out 10% of something, the decimal point moves back a spot, so 1823 becomes 182.3. The exception is for fractions, where it moves up. It does this because a percentage of something is creating a smaller number, and if you have a fraction, then the number you have is even smaller, shown by using extra 0's after the decimal point, so using the 10% example, 0.5 would become 0.05.

So I have established that 10% of 1823 is 182.3, now I need 5%, so I halve my 182.3 to make 91.15. You can also do this by finding 1% of the number and adding it to itself a number of times that equals the percentage you need. to find one percent, push the decimal point back another place. In this case 1823 now become 18.23. If you add 18.23 together 5 times, it = 91.15.

So in a nutshell, find the total weight in grams, 5 the percentage you need, then make the sum easier to manage.
