1. What is a Watt to Unit Calculator for Bangladesh?

Definition: This calculator converts electrical power consumption (in watts) over time (in hours) to electricity units (kWh) as used in Bangladesh.

Purpose: Helps consumers estimate their electricity bill by calculating the units consumed by appliances.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Units — Electricity consumption in kilowatt-hours (kWh)
• Watts — Power rating of the appliance
• Hours — Duration of usage
• 1000 — Conversion factor from watts to kilowatts

Explanation: The formula converts watt-hours to kilowatt-hours, which is how electricity is billed in Bangladesh.

3. Importance of Unit Calculation

Details: Understanding unit consumption helps in budgeting electricity costs and identifying energy-hungry appliances.

4. Using the Calculator

Tips: Enter the appliance's wattage (found on its label) and the number of hours it's used. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's wattage?
A: Check the label or manual. If only amps are listed, multiply amps by voltage (220V in Bangladesh) to get watts.

Q2: What's the average unit consumption in Bangladesh?
A: Average household uses 200-400 units/month, but this varies greatly by appliance usage and family size.

Q3: How does this relate to my electricity bill?
A: Multiply the units by your per-unit rate (varies by usage tier in Bangladesh) to estimate costs.

Q4: What if my appliance has variable power?
A: Use the maximum wattage for worst-case estimates, or average if you know the duty cycle.

Q5: Does this account for power factor?
A: This simple calculator doesn't. For precise calculations with inductive loads, multiply by power factor (typically 0.8-0.9).
