A Few Items of Information

The unit kWh is a unit of energy, which is power multiplied by
time. Multiply the power of the equipment (measured in W or kW) by time used
(measured in h) and you get the energy in kWh.

Examples:

A power of 1 kW over a time of one hour is one kWh. A 100 W (0.1 kW) bulb left
on for 5 hours uses 0.1 x 5 = 0.5 kWh.

If your home uses an average of 500 W (0.5 kW) then it will consume 12 kWh per
day (24 h).

Also not the correct capitalization. Only the W (Watt) is capitalized, the k
(kilo = 1000) prefix and the time unit h (hour) are not.

=============================================================

1 KWh, is 1 kilowatt per second, for 1 hour, or 1KW x 3600 seconds (3,600,000
watts)

================================================================================================

**Question:**

Oki Data specifies power consumption in Watts. How is that converted to
Kilowatts per hour?

**Answer:**

The Unit kWh actually means Kilowatts multiplied by hours.

The correct formula to calculate kWh from W is:

kWh = (Watts/1000) * hours

Where hours is the time in hours the unit is switched on.

To find the power consumption for a 95Watt unit during an 8 hours working day:

95W/1000 * 8h = 0.76kWh

If the same machine is always on and you want to know the consumption for one
month, the formula is:

95W/1000 * 24h * 30 = 68.4kWh
