E means raised to the power of ten.

x E y is shorthand for X * 10^y.

(See http://en.wikipedia.org/wiki/E_notation#E_notation)

1E-12 and 10^-12 are the same number, specifically 1,000,000,000,000.
10E-12 is one order of magnitude (ten times) larger.

What is the difference between 1E-12, 10E-12, and 10^-12?

E means raised to the power of ten.

E means "times ten raised to the power" (as, indeed, it says in the
wikipedia reference below) which is not the same thing as "raised to the
power of ten".

x E y is shorthand for X * 10^y.

(See http://en.wikipedia.org/wiki/E_notation#E_notation)

Right.

1E-12 and 10^-12 are the same number, specifically 1,000,000,000,000.

You mean, of course, 1/1,000,000,000,000

10E-12 is one order of magnitude (ten times) larger.

(... than 1E-12) - correct.
