What Is This Tool?

This converter transforms values from Btu (th)/pound, a unit expressing energy content per mass of fuel, into pound/horsepower/hour, which indicates the fuel mass consumed per unit of engine power over time. It's useful for evaluating fuel efficiency and comparing fuel consumption rates in various industries.

How to Use This Tool?

  • Enter the fuel's energy value in Btu (th)/pound into the input field.
  • Select the target unit pound/horsepower/hour for conversion.
  • Click the convert button to see the equivalent fuel consumption rate.
  • Review the output to assess fuel efficiency or system performance.

Key Features

  • Converts between thermochemical British thermal unit per pound and pounds per horsepower-hour.
  • Supports fuel efficiency and mass-based energy analysis.
  • Useful for industries like power generation, automotive, aerospace, and marine.
  • Browser-based and simple to use with clear unit definitions.
  • Provides precise conversion based on standardized thermochemical Btu values.

Examples

  • 1 Btu (th)/pound equals approximately 2546.14 pound/horsepower/hour.
  • 0.5 Btu (th)/pound converts to around 1273.07 pound/horsepower/hour.

Common Use Cases

  • Calculating fuel mass flow from energy demand for boilers and combustion systems.
  • Comparing the specific energy of fuels like coal, diesel, or biomass.
  • Reporting brake specific fuel consumption (BSFC) for automotive and piston engines.
  • Estimating fuel burn and planning range for aircraft gas-turbine or turboprop engines.
  • Evaluating fuel consumption in industrial generators and marine engines during testing.

Tips & Best Practices

  • Ensure fuel measurements use standardized thermochemical Btu definitions.
