Homework Help: Convert voltage to acceleration

  1. Mar 30, 2012 #1
    May i know how to convert voltage to acceleration from accelerometer ?

    output voltage = 2.5 v and sensitivity of accelerometer is 9.9mv/g
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Look at the units you're starting with and what the units are for the conversion constant ("sensitivity"). Do you want to multiply or divide to get the units you're looking for?

    can voltage divide sensitivity of accelerometer to get acceleration result ?

    v / mv/g = g

    hi manutdkaki :smile:
    that's right …

    the beauty of units is that they multiply and divide exactly like ordinary fractions :smile:

    v / (mv/g) = vg/mv = g/m = kg :wink:

    v is voltage
    mv = milivoltage
    g= acceleration

    got any book source to prove it ?

    Units are treated as variables. So you can prove it with elementary algebra. I guess you need a book on algebra.
