Dimensions chart

  1. Jan 11, 2006 #1
    Sorry if its here somewhere but I couldn't find it, where can I find a chart/list for quantities listing their dimensions using the MLtT and FLtT systems and also give the typical SI and English units?

    Go to www.efunda.com/units/ and you will find a list of unit categories. Click on any one of them ... for example, click on "density". Then you'll get a list of various units of density. Click on any one of them ... for example, click on "grams per cubic centimeter". Then you'll get the dimensional units in each of three systems you want.

    they want me to pay a fee?

    Otherwise, use the index in your physics textbook
    (most will at least have a table with SI units)

    What gave you the idea that www.efunda.com charges a fee?? That website is free ... anyone can read it without paying any fees!!

    Did you actually visit the site before you asked your question about whether they charge a fee?

    Sure I visited the site and after about 2 minutes a pop-up said that my free session was about to expire and everything that I clicked on led me to the membership page, which has a $6/month fee. (http://www.efunda.com/about/about.cfm) This page says that they charge a fee to pay their engineers who keep the information provided "credible"

    I no longer have a physics book, this is for a Thremo-Fluids class, I can't believe that they don't have this information in there and I can't believe that this kind of stuff woud be hard to find on the internet. I know most of the SI units but the MLtT and FLtT is a bit vague. Anywhere else I can find it?

    It absolutely does. Some sections are not available if you are not a supporting member as well.

    You can also try EngNet's list of units here:

    Or try this:

    Thanks, I guess that I don't understand how to indicate the dimensions in the MLtT system. Does that mean that I'm supposed to express angular velocity for example with some combination of MLtT? I have not seen that anywhere, most of these sights have the common dimension and derived dimensions but I have not seen "Modulus of Elasticity" at any of these sites and certainally not in therms of MLtT? Any suggestions of where I go from here?
