What Is This Tool?
This tool converts power values from MBH, a unit representing heat output in HVAC systems, to volt ampere [V*A], the unit measuring apparent power in alternating-current electrical circuits.
How to Use This Tool?
-
Enter the power value in MBH that you want to convert.
-
Select MBH as the input unit and volt ampere [V*A] as the output unit.
-
Click convert to get the corresponding power value in volt ampere [V*A].
-
Use the conversion formula provided to verify or manually calculate conversions if needed.
Key Features
-
Converts power from MBH (thermal power) to apparent electrical power in volt ampere [V*A].
-
Provides a clear conversion formula and rate for easy calculation.
-
Useful in HVAC design, electrical engineering, and equipment specification.
-
Browser-based and user-friendly for quick unit conversions.
Examples
-
5 MBH is equal to 5 × 293.0710701722 = 1465.36 Volt ampere [V*A].
-
10 MBH converts to 10 × 293.0710701722 = 2930.71 Volt ampere [V*A].
Common Use Cases
-
Rating furnace, boiler, or water-heater capacity in HVAC systems using MBH and relating it to electrical power ratings.
-
Sizing heating and cooling loads in building energy calculations and equipment selection.
-
Specifying transformers, UPS, and generators by their volt ampere capacity in electrical distribution design.
Tips & Best Practices
-
Always confirm whether you require apparent power or real power for your application before conversion.
-
Use this conversion to compare heating power in MBH to electrical apparent power, but be cautious about different power factors.
-
Refer to the conversion formula and examples for accurate manual calculations.
Limitations
-
Conversion assumes equivalence between thermal power (MBH) and electrical apparent power (V*A), which doesn't account for power factor effects.
-
Volt ampere values represent apparent power and may differ from actual usable watts unless power factor is factored in.
-
The conversion provided is approximate since it relates heat rate units to electrical supply characteristics.
Frequently Asked Questions
-
What does MBH represent?
-
MBH is a non-SI unit of power equal to 1,000 British thermal units per hour, used to express heat output or input rates in HVAC and heating equipment.
-
What is a volt ampere [V*A]?
-
Volt ampere is the unit of apparent power in AC circuits, calculated as the product of RMS voltage and RMS current, representing total delivered power.
-
Can I use this conversion to determine actual electrical power consumption?
-
No, because volt ampere measures apparent power and doesn't account for power factor, it may not equal actual usable power in watts.
Key Terminology
-
MBH
-
A unit representing 1,000 British thermal units per hour used to express heat power in HVAC systems.
-
Volt ampere (V*A)
-
Unit of apparent power in AC circuits, calculated as RMS voltage multiplied by RMS current.
-
Apparent power
-
The total power in an AC circuit without consideration of power factor, expressed in volt amperes.
