Conversion

Conversion is a number that multiplies the raw Totalizer result. It is used to convert the rate tag units to the proper units for the totalization.

For TimeWeighted totals, the total is computed with the assumption that the rate tag is in units per day. If the rate tag units are not in units per day, use Conversion to convert the rate tag to units per day.

For example, suppose the rate tag units are megawatts (MW) and the desired total is kilowatt hours (kWh). First, convert the input rate tag to units per day: 1 MW = 1 MJ/sec, so the conversion factor is (1 MJ/sec) x (86400 sec/day). The totalizer tag's unit of measure would then be MJ. Next, convert the totalized value from MJ to kWh. 1 kWh = 3.6 MJ, so the conversion factor is:

(1 MJ/sec) x (86400 sec/day) x (1 kWh/3.6 MJ) = (24000 kWh/day)

Thus, in this case you would set Conversion to 24000.

For EventWeighted totals, use Conversion to convert the rate tag units to the desired units of the total. For example, if the rate tag units are kilograms and the desired total is grams, set Conversion to 1000.
