6E-07 is 6 x 10^-7 .... which is of course 0.0000006

^ represents 'to the power of'.

On calculators, the E is sometimes denoted "exp", which is short for "exponential". The phrase "exponential notation" is another name for "scientific notation". Scientific notation is used for expressing numbers that are too big or too small to be easily written in their decimal form.
