How to Calculate Electricity Units From Meter Reading
Subtract the previous meter reading from the current reading. For a standard residential meter with multiplier 1, the result is the number of units consumed during the billing period.
If your bill or meter record shows a multiplying factor, multiply the reading difference by that factor. One electricity unit equals one kilowatt-hour (kWh).
Example
If the previous reading is 12,450 and the current reading is 12,725, the difference is 275. With a multiplier of 1, consumption is 275 units. Over 30 days, average daily use is about 9.17 units.
Why Your Bill May Be Higher Than Units × Rate
The meter-reading calculation gives consumption, not the final UPPCL payable amount. Your electricity bill can also include slab-based energy charges, fixed charges based on sanctioned load, FPPAS, electricity duty, arrears, rebates and other adjustments.

Frequently Asked Questions
What if my current reading is lower than the previous reading?
Check that you entered the readings correctly. A lower current reading can also occur after meter replacement or rollover, in which case you should use the readings and adjustment shown on the official bill.
Is one meter unit equal to one kWh?
For normal billing, one electricity unit is one kilowatt-hour (kWh), subject to any meter multiplier shown for the connection.
