1. What is a kWh per Hour Cost Calculator?

Definition: This calculator estimates the hourly operating cost of electrical devices based on their power consumption and electricity rates.

Purpose: It helps homeowners and businesses understand the cost implications of running electrical equipment.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ C = P_{kW} \times C_{kWh} \]

Where:

$ C $ — Cost per hour ($ or £)
$ P_{kW} $ — Power consumption (kilowatts)
$ C_{kWh} $ — Cost per kilowatt-hour ($/kWh or £/kWh)

Explanation: The power consumption is multiplied by the electricity rate to determine the hourly operating cost.

3. Importance of kWh Cost Calculation

Details: Understanding energy costs helps in budgeting, comparing appliance efficiency, and making informed purchasing decisions.

4. Using the Calculator

Tips: Enter the device's power consumption in kW (check nameplate or specifications) and your local electricity rate (default $0.12/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my device's power consumption?
A: Check the nameplate or specifications (often in watts - divide by 1000 to get kW), or use a power meter.

Q2: What's a typical electricity rate?
A: Rates vary by location, but $0.10-$0.30 per kWh is common in the US. Check your utility bill for exact rates.

Q3: Can I calculate daily/monthly costs with this?
A: Yes, multiply the hourly cost by hours used per day/month. We may add dedicated calculators for these.

Q4: Does this include all energy costs?
A: This calculates direct electricity costs only. Additional fees (demand charges, taxes) may apply.

Q5: Why use kW instead of kWh?
A: kW measures instantaneous power, while kWh measures energy over time. We convert to cost per hour.
