Convert voltage to acceleration

[manutdkaki]

May i know how to convert voltage to acceleration from accelerometer ?

output voltage = 2.5 v and sensitivity of accelerometer is 9.9mv/g

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?

 

[manutdkaki]

can voltage divide sensitivity of accelerometer to get acceleration result ?

v / mv/g = g

hi manutdkaki

v / mv/g = g

that's right …

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

v / (mv/g) = vg/mv = g/m = kg ​

 

[manutdkaki]

v/(mv/g)

v is voltage
mv = milivoltage
g= acceleration

got any book source to prove it ?
thanks

does this help … http://www.owlnet.rice.edu/~labgroup/pdf/Dimensions_units.htm ?

i hope can get from instrumentation book to prove it . thanks tiny-tim

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