Electricity Consumption

The Electricity Consumption calculator computes the power consumed over a period of time in kilowatt hours.

INSTRUCTIONS: Choose units and enter the following:

• (P) Power Usage to operate electrical appliance or motor
• (T) Operating Time which is the duration that the power is being used (consumed).

Electric Power Consumption (PC): The calculator power consumption in kilowatt hours.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for Electricity Consumption is:

   PC = P • T

where:

• PC is the total power consumption
• P is the average power over the period of time
• T is the duration of time

• Voltage Drop: This computes the voltage drop in volts and as a percentage over a length of cable (wire) based on length of wire, gauge, wire material, temperature range and phase.
• Wire Gauge Choice for Safe Voltage Drop: This determines the lightest gauge of wire that can be used over a run (circuit) that maintains adequate voltage.
• Circular Mils and Voltage Drop: This computes voltage drop based on wire diameter in circular mils instead of wire gauge.
• Electricity Usage Cost: This computes the cost of electricity for the use of a piece of equipment based on the power consumption rate, duration and cost of electricity.
• Electricity Consumption: This computes the amount of electricity consumed by an electrical appliance or motor over time.
• Rolling Offset: This computes the travel (T) and run (R) of a rolling offset used in conduit piping based on the offsets and angles.
• Diameter of AWG Wire: This provides the diameter of wire based on the American Wire Guide (AWG) gauge in mils and millimeters, and it also provide the cross-section area in square millimeters.
• P = V² / R: This computes power (Watts) based on the voltage (V) and resistance (R).
• DC to AC Converter: Computes the approximate voltage of Alternating Current (AC) from the voltage of Direct Current (DC).
• Diameter to Circular Mils: Computed the circular mils of a wire and the cross-section area based on the wire's diameter.
