Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Horsepower and Newton meter measure different quantities, so no single result applies.

Formula
Horsepower (hp) measures power, while Newton meter (N m) measures torque (rotational force). These are different physical quantities, so there is no single multiplication factor that converts one into the other.
hp relates to its own power base unit by a factor of 745.7. N m relates to its own torque (rotational force) base unit by a factor of 1.

Frequently asked questions
Can Horsepower be converted to Newton meter?
Not directly. Horsepower measures power and Newton meter measures torque (rotational force). Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Horsepower used for?
The Horsepower (hp) is a unit of power. Mechanical horsepower.
What is Newton meter used for?
The Newton meter (N m) is a unit of torque (rotational force). Newton meter is the SI torque unit.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since Horsepower and Newton meter don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Horsepower to instead?
Use another power unit, such as one of the related Horsepower conversions linked below.
What should I convert Newton meter to instead?
Use another torque (rotational force) unit, such as one of the related Newton meter conversions linked below.

About this conversion
This page compares Horsepower (hp) and Newton meter (N m) within the engineering converter.
Mechanical horsepower. Newton meter is the SI torque unit.
Because Horsepower measures power and Newton meter measures torque (rotational force), the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
