+4473 Standard deviation refers to how far away data values are from the mean.
For example, if we had data with the following values: 5,5,5,5
The mean is 5*4/4 = 20/4 = 5.
The standard deviation is 0 because all the values are 5.
However, if we had the following: 0,5,5,100
The mean would now be [(0+5+5+100) / 4] = 110 / 4 = 27.5.
Note: The mean is 27.5 and none of the values are exactly 27.5 so our standard deviation is not 0, but...a different number!

+3454 You have to tell us which measurement you want this converted to.
You can actually do this on the website's calculator. Here's how:
Go to the website's homepage. This can be found at this link: http://web2.0calc.com/
Click "Scientific" and change this to "Unit converter"
Now click "length," because this is the type of measurement we're dealing with.
Now in the first box type in how much of the unit you have. In this case it would be 1505.91.
Then, in the circled box select what measurement you have (in this case it would be inches)
And in the highlighted box, select the measurement you want to convert this to.
Finally, press the equal sign to compute this.
