RCF Calculator



In the world of laboratory science and research, calculating the Relative Centrifugal Force (RCF) is a crucial task. RCF, also known as the g-force, helps researchers determine the effective force applied to samples in a centrifuge. To simplify this calculation, we’ll guide you through creating an HTML code for an RCF calculator. This calculator will take two essential parameters into account: RPM (Revolutions Per Minute) and the radius of rotation.

How to Use

Using our HTML-based RCF calculator is straightforward. Follow these steps:

  1. Input the RPM (Revolutions Per Minute) in the designated field.
  2. Input the radius of rotation (r) in the specified field.
  3. Click the “Calculate RCF” button.

The calculator will instantly compute the RCF based on the formula provided below.


The formula for calculating RCF (Relative Centrifugal Force) is as follows:

RCF = (RPM)^2 * 1.118 * 10^-5 * r


  • RCF is the Relative Centrifugal Force in g-force units.
  • RPM stands for Revolutions Per Minute.
  • r represents the radius of rotation.


Let’s say you’re conducting a centrifugation experiment with an RPM of 4000 and a radius of rotation of 0.05 meters (50 mm). Using the formula:

RCF = (4000)^2 * 1.118 * 10^-5 * 0.05 = 8.944 g

So, the RCF for this scenario would be 8.944 g.


Q1: What is RCF (Relative Centrifugal Force)?

A: RCF, also known as the Relative Centrifugal Force or g-force, is a measure of the effective force experienced by particles or samples in a centrifuge. It is used in centrifugation experiments to separate components based on their density.

Q2: Why is RCF important in centrifugation?

A: RCF is important because it determines the sedimentation of particles in a centrifuge. It helps researchers control the force applied to their samples, ensuring effective separation and pelleting.

Q3: Can I use this RCF calculator for different units of RPM and radius?

A: Yes, you can use this RCF calculator for different units of RPM and radius as long as you ensure that the units are consistent. If you use RPM in revolutions per second (rps), you should also convert the radius to meters if it’s given in a different unit.

Q4: How can I integrate this calculator into my HTML form?

A: To integrate this calculator into your HTML form, you can create input fields for RPM and the radius of rotation, and a button to trigger the calculation. Then, use JavaScript within your HTML page to perform the RCF calculation when the button is clicked.


Calculating RCF is an essential task in various laboratory applications. By creating an HTML-based RCF calculator with a user-friendly interface, you can streamline this process and ensure accurate results. Feel free to customize and integrate this calculator into your HTML forms to make your research and experimentation more efficient.
