1. What is a Boiler HP to kW Calculator?

Definition: This calculator converts boiler horsepower (BHP) to kilowatts (kW) using a standard conversion factor.

Purpose: It helps engineers and technicians convert between these common power measurement units used in boiler systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power in kilowatts
• \( BHP \) — Boiler horsepower

Explanation: One boiler horsepower is equivalent to approximately 9.81 kilowatts.

3. Importance of Power Unit Conversion

Details: Accurate conversion between units ensures proper system specification, performance evaluation, and equipment compatibility.

4. Using the Calculator

Tips: Enter the boiler horsepower value (must be > 0) and the calculator will automatically compute the equivalent power in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BHP and regular HP?
A: Boiler HP is a specialized unit for boiler power output, while mechanical HP measures engine power. 1 BHP = 9.81 kW vs 1 HP = 0.746 kW.

Q2: Why is the conversion factor 9.81?
A: This comes from the original definition of boiler horsepower as the energy needed to evaporate 34.5 pounds of water per hour at 212°F.

Q3: Is boiler horsepower still commonly used?
A: Yes, especially in the US for rating boiler systems, though kW is becoming more common internationally.

Q4: How precise is this conversion?
A: The 9.81 factor is standardized, though some references may use 9.8095 for slightly more precision.

Q5: Can I convert kW back to BHP?
A: Yes, divide kW by 9.81 to get boiler horsepower.
