Question 1024972: I was using an online calculator to figure kinetic energy. Knowns are mass and velocity (mass = 395,000 lbs and velocity is 500 mph.) The answer given is 3.3011e+9 ft. lbs., but I don't know what this means. Can someone decipher this, please?

This is called scientific notation.
It looks like:

-------------------
The is always a units digit. You would
NOT have:

even though it is the same value
So you have a units digit followed by
as many other significant digits that you need
-------------------
Then there is a multiplier which is 10 raised to
a power which can be any number, positive
or negative, for example:

This is the reciprocal of my example.
-------------------
The way you presented it:
3.3011e+9 is just another way of saying:
, and if you expand it:

( 9 places after decimal point )
