Mostly both are units of pressure. when we measure the very
low pressure than it is expressed in mmwc else higher
pressures are measured in kg/cm2. low pressure can also be
used for but the error in values will be more.
Basically 10000 mmwc is 1 kg/cm2 a.In thermal power plant mmwc is most useful in boiler side.
