What does one pound-foot per second represent?

It is an imperial unit of power that measures how much work is performed per second using one pound-force foot of torque.

What is horsepower (550 ft*lbf/s)?

It is a mechanical power unit defined as 550 foot-pound-force of work done per second, commonly used for rating engines and machinery.

Can I use this converter for metric horsepower?

No, this conversion specifically uses the mechanical horsepower definition of 550 foot-pound-force per second and does not include metric horsepower.

It facilitates clear comparisons and conversions within engineering and technical fields.

How to Use This Tool?

Enter the power value in pound-foot per second into the input field
Select pound-foot/second as the input unit and horsepower (550 ft*lbf/s) as the output unit
Click convert to get the equivalent horsepower value

Key Features

Supports conversion between pound-foot per second and mechanical horsepower (550 ft*lbf/s)
Based on imperial measurement units used in automotive and mechanical engineering
Calculates power transfer rates important for engines, motors, pumps, and compressors

Examples

100 pound-foot/second converts to approximately 0.18181818 horsepower (550 ft*lbf/s)
500 pound-foot/second converts to roughly 0.9090909 horsepower (550 ft*lbf/s)

Common Use Cases

Calculating mechanical power from torque and rotational speed using imperial units
Estimating output of small motors, hand tools, and shaft power with US customary measurements
Rating internal-combustion engines and garden equipment using horsepower
Converting legacy specifications into standardized power units for analysis or comparison
Sizing pumps, compressors, and motors within imperial unit frameworks

Tips & Best Practices

Use the converter when working with torque and rotational speeds expressed in imperial units
Be mindful of different horsepower definitions that exist outside mechanical horsepower
Double-check unit selections to avoid mixing metric and imperial powers
Apply conversions carefully for very small or very large values due to rounding considerations

Limitations

Conversion relies on consistent mechanical definitions of pound-foot and horsepower
Does not account for alternate horsepower definitions such as metric horsepower
Rounding may impact precision for extremely small or large measurements
