1. What is a Power Consumption Calculator for Malaysia?

Definition: This calculator estimates the energy consumption in kilowatt-hours (kWh) based on the power rating of an appliance and its usage time.

Purpose: It helps Malaysian households and businesses estimate electricity usage and costs according to TNB tariffs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( P \) — Power rating of appliance (watts)
• \( t \) — Time of usage (hours)

Explanation: The power in watts is multiplied by time in hours, then divided by 1000 to convert to kilowatt-hours (kWh), the standard billing unit in Malaysia.

3. Importance of Power Consumption Calculation

Details: Understanding energy usage helps in budgeting electricity costs, comparing appliance efficiency, and reducing carbon footprint.

4. Using the Calculator

Tips: Enter the appliance's power rating (in watts) and your daily usage time (in hours). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my appliance's power rating?
A: Check the label, manual, or specifications sheet. Typical ratings: LED bulb (10W), Fan (50W), Air Conditioner (1000W).

Q2: How does this relate to my TNB bill?
A: TNB charges per kWh used. Multiply the result by your tariff rate (RM/kWh) to estimate cost.

Q3: Should I use average or peak power rating?
A: For accurate estimates, use the average power consumption during normal operation.

Q4: Can I calculate monthly consumption?
A: Yes, multiply daily usage by 30 or enter total monthly hours directly.

Q5: Why divide by 1000?
A: This converts watt-hours to kilowatt-hours (1 kWh = 1000 watt-hours), the standard billing unit.
