The area between the mean and 1 standard deviation above or below the mean is about 0.3413 or 34.13%
If you're talking about geometry, then the "mean" = "average". In that case 50% (half) of surface area is above the mean and 50% (half) is below.
4.55% falls outside the mean at 2 standard deviation
34.1% of the data values fall between (mean-1sd) and the mean.
eg 5 10 15, the mean would be 10 and if we want the mean percentage its the percentage of the total so 10/20x100/1, which is 50%
the total grades of the student in a particular subject area divided by the total number of students multiplied by 100

There must be a formula, but in the mean time there is a handy site that does it for you. [See related link below for the converter]
One standard deviation for one side will be 34% of data. So within 1 std. dev. to both sides will be 68% (approximately) .the data falls outside 1 standard deviation of the mean will be 1.00 - 0.68 = 0.32 (32 %)
