Electricity Units Formula:
From: | To: |
Definition: This calculator converts electrical power consumption from watts to units (kWh) based on usage hours, specifically designed for Pakistan's electricity billing system.
Purpose: It helps consumers estimate their electricity bills by calculating how many units they consume based on appliance wattage and usage time.
The calculator uses the formula:
Where:
Explanation: The formula converts watts to kilowatts (by dividing by 1000) and multiplies by hours to get kilowatt-hours (units).
Details: In Pakistan, electricity is billed by units (kWh). Understanding your consumption helps manage bills and identify energy-saving opportunities.
Tips:
Q1: What's the cost per unit in Pakistan?
A: Electricity rates vary (typically 16-50 PKR/unit) based on consumption slabs and your distribution company (e.g., LESCO, IESCO).
Q2: How can I find my appliance's wattage?
A: Check the appliance label, manual, or search online for typical wattages of similar devices.
Q3: Does this account for power factor?
A: This simple calculator assumes resistive loads. For motors or inductive loads, actual consumption may be higher.
Q4: How accurate is this for monthly bills?
A: For better accuracy, calculate each appliance separately and sum the results, then multiply by 30 days.
Q5: What's the difference between watts and units?
A: Watts measure power (instantaneous), while units (kWh) measure energy consumption over time.
