kW to Torque Calculator

Understanding the relationship between power (kW) and torque (Nm) is essential in engineering, automotive, and mechanical fields. For professionals and enthusiasts alike, our advanced kW to Torque Calculator is designed to provide precise and instant results, making your calculations hassle-free.

This article will guide you on how to calculate torque from kilowatts and RPM, explain the relationship between torque and power, and demonstrate how to use our calculator effectively.

What Is Torque and How Does It Relate to Power (kW)?

Torque refers to the rotational force applied to an object, typically measured in Newton-meters (Nm). The relationship between torque and power (measured in kilowatts) is defined by rotational speed (RPM). The equation is as follows:

$$\begin{gathered} \text{Torque (Nm)}= \\ frac\text{Power (kW)} \\ times9550\text{RPM} \end{gathered}$$

This formula bridges the gap between torque, power, and rotational speed, ensuring precise mechanical calculations. For example, knowing how much torque a 2.7 kW motor generates can determine its capability in driving machinery.

How to Use Our kW to Torque Calculator

Our kW to Torque Calculator simplifies the process. Here's how you can use it effectively:

1. Input Power (kW): Enter the power rating of your motor or equipment in kilowatts.
2. Input Rotational Speed (RPM): Specify the rotational speed of the shaft in RPM.
3. Get Instant Results: Click on the “Calculate” button to view the torque output in Newton-meters (Nm).

For instance, if you input 2.7 kW and 1500 RPM, the calculator will instantly show the torque value.

Practical Example

These values demonstrate how torque varies with power and RPM. Understanding this relationship is crucial for designing motors and analyzing mechanical systems.

How to Calculate Torque Without Power

If power (kW) is unknown, torque can still be calculated using alternative parameters such as force and radius:

$$\begin{gathered} \text{Torque (Nm)}= \\ textForce(N) \\ times \\ textRadius(m) \end{gathered}$$

However, in most practical scenarios, knowing power and RPM simplifies the process.

FAQs

How do you convert kW to torque?

Use the formula: 

$$\begin{gathered} \text{Torque}= \\ frac\text{kW} \\ times9550\text{RPM} \end{gathered}$$

What is the relationship between torque and kW?

Torque and power are directly related, with RPM acting as the intermediary. Higher power at lower RPM results in greater torque.

How much torque does a 2.7 kW motor produce at 1500 RPM?

Using the formula, 

$\text{Torque} = \\frac{2.7 \\times 9550}{1500} = 17.18 \, \text{Nm}$

Can I calculate motor torque without knowing power?

Yes, torque can be determined using force and radius if power is unavailable.
