Hello Dear Matlab users,
I have one small quesry on Unit conversion. Can anybody help me to covert unit of Voltage(V) to acceleration(m/s^2) and in speed (m/s)
Voltage=1 V
Thank you

The last term on the right side can be rewritten to acceleration and speed.

Thank you here is the code:
data(:,2) is in Voltage from picoscope
data(:,1)=(data(:,1)-data(1,1))/1e3; % time in s
data(:,2)=data(:,2);% Voltage%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
data(:,2)=data(:,2)/0.0102;%Unit of Acceleration in [m/s^2]%%%%%%%%%%
%data(:,2)=data(:,2)/0.1;%Unit of Acceleration in [g]%%%%%%%%%%%%%%%%

I dont think it is possible to reconstruct what is meant here without more informations:
data = 10 % 10 Volt for example
data = data / 0.0102 % same as multiplying by 98,1 m/s^2 (!) --> 10 g
data = data / 0.1 % again times 10
>> Untitled
data =
10
data =
980.3922
data =
9.8039e+03
% --> You have now 10 V * 9,81 m/s^2 (which IS g) * 10 some unknown unit * 10 also unknown unit

Thank you.I had similar doubt. I need to ask script developer direct.
