Q. The conversions do not work! When I click the "Convert Now" button, nothing happens.

A. The conversions will not work until the page has finished loading. Sometimes the banner ads take a few extra seconds to load. When that happens, click the "Stop" button in the toolbar and try the conversion again. You can also try the "Refresh" or "Reload" button, depending on which browser you use. (Yes, we know how most of you feel about banner ads, but the ads pay for the site so you can continue to use it for free.)

Q. I got an answer that looks like this: 2.64e+06    Or like this: 5.3e-08   What does that mean?

A. The "e" stand for exponent. So 2.64e+06 is the computer program's way of saying 2.64 x 10 raised to the 6th power, or 2,640,000. If your result was 5.3e-08, then the answer would have been 5.3 x 10 raised to the negative 8th power, or 0.000000053

Basically, the exponent tells you how many places to move the decimal point. This way of expressing large numbers as powers of 10 is called "scientific notation." For more information, visit New York University's page on scientific notation.
