    [SOLVED] I cant seem to understand my Metric System Chart

    I was given a chart of the metric system, but I cant seem to understand how the conversions work. Lets say I want to convert micro into milli. For micro, the chart says 10^-6, and 0.000001. For milli, it says 10^-3 and 0.001.

    The way I tried to do this by typing in 0.000001 x 10^-3, not sure if that's what you're supposed to do when converting it, and my TI-83 came back with an answer of 1E-9, which I dont understand at all. I think there was a way to make the TI-83 show all the numbers, but I cant remember how.

    I'm still need to how the metric system works, and i'm trying to figure out how to convert 8.9mL into microliters, and 1/2 Quart into milliliters.

    I'm hoping that someone here will know how to explain this so that I can understand it. Looking at the chart just seems to confuse me. The whole conversion process is pretty much what I dont understand. And how I can get it to work with my calculator.

    Hi fb280,

    To the TI-83, 1E-9 means 1 \times 10^{-9}.

    I don't think there is.

    Here's how I would approach your conversion. I would use a set of ratio products to arrive at my desired result. Like this:

    Convert 8.9 milliliters( mL) to microliters( \mu L)

    \frac{8.9 mL}{1}\cdot \frac{1000 \mu L}{1 mL}=8900 \mu L

    Convert .5 quarts to milliliters.

    \frac{.5 q}{1}\cdot\frac{.946352 L}{1 q}\cdot \frac{1000 mL}{1L} \approx 473.176 mL.

    Notice that in the products, all the units of measure cancel out except for the one you are trying to convert to. Neat, huh?

    I had to look up the number of liters in a quart (rounded off).

    I think I might know how to convert it now after looking through the chart more. But I wasnt sure until I read your reply, so thanks for the help. There is one thing i'd like to make sure of though.

    If the ti-83 comes out with a number like 8E7, would I just move the decimal place to the right by eight places?

    No. 8E7 means 8 times ten to the 7th power. 8.0 \times 10^7.

    8E7 means 80,000,000.
