Energy conversions and calculations — watts to kilowatts, units to cost, appliance consumption — are essential for understanding your electricity bill in Pakistan. This 500 Units Electricity Bill Calculator handles one of those conversions so you can read your energy numbers correctly.
The calculation converts between the standard energy units — watts, kilowatts, kilowatt-hours and units (where 1 unit = 1 kWh) — using the exact relationships between them.
Your electricity bill charges per unit (kWh), while appliances are rated in watts. Converting between the two is the first step to understanding what each appliance costs to run — and to spotting where your bill comes from.
Use the tool with the appliance-cost calculator on this site to build a complete picture of your household's energy use and the savings available from switching to efficient appliances.

Frequently Asked Questions
What is the bill for 500 units in Pakistan?
The bill depends on your slab rate (Rs 15–45 per unit), FPA surcharge and fixed charges. At a typical Rs 32/unit the energy charge alone is Rs 16,000, before FPA and fixed charges. Adjust the rate to match your bill's per-unit figure.
How many watts are in a kilowatt?
1,000 watts equals 1 kilowatt. A 1,500 W appliance uses 1.5 kW, and running it for one hour consumes 1.5 kWh — which is 1.5 units on your electricity bill.
What is a unit of electricity in Pakistan?
One unit is one kilowatt-hour (kWh) — the energy used by a 1,000 W appliance running for one hour. Your bill charges a per-unit rate for total kWh consumed.
