wattmeter is constructed such that it read only power on a single scale. Only single scale will avilable to read the measured power. In order to take the acuurate reading just we measure the reading and we will multiple along with factor called multificaion factor. That's depends on on which voltage knob we connected and also the current.
Multification factor can be dtermind by:
Multification factor =(voltage range*current range*pf)/Max scale deflection...
MF= (current coil rating* pressure coil rating)/ full scale deflection
If you want to know how many WATTS you need to multiply Volts x Amps
Volts x Amps = Watts
The formula for the multiplication factor for a watt meter is simple. It is: MF = (main PT ratio x main CT ratio x meter constant)/(meter PT ratio x meter CT ratio).
It's usually printed on the face of the meter. It will be something like "kH 7.2" or "1.0kH". Older, analog meters are usually 7.2; digital meters are usually 1.0.
CT ratio x PT ratio gives the multiplying factor

my question is what is the formula for pressure?
Yes, there is a formula for calculating labor cost, which is: Labor Cost = Number of Hours Worked x Hourly Rate This formula can be adjusted depending on additional factors like overtime or bonuses.
