1. What is RPM to G Force Conversion?

Definition: This calculator converts rotational speed (RPM) and radius into relative centrifugal force (RCF) expressed in g-force.

Purpose: It's essential for laboratory centrifuges, industrial equipment, and any application involving rotational motion.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — Relative centrifugal force (g-force)
• \( RPM \) — Rotations per minute
• \( r \) — Rotational radius (cm)
• \( 1.118 \times 10^{-5} \) — Conversion constant

Explanation: The formula calculates the acceleration experienced at a point rotating at a certain speed and distance from the center.

3. Importance of G Force Calculation

Details: Accurate g-force calculation is critical for proper centrifuge operation, material testing, and safety in rotating equipment.

4. Using the Calculator

Tips: Enter the RPM value and the rotational radius in centimeters. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is radius measured in centimeters?
A: The standard scientific formula uses centimeters. For inches, convert to cm (1 inch = 2.54 cm) before calculation.

Q2: What's a typical RPM range for centrifuges?
A: Laboratory centrifuges typically operate between 1,000-15,000 RPM, producing 100-20,000 g.

Q3: How does g-force affect materials?
A: Higher g-forces cause greater separation of materials by density and can stress mechanical components.

Q4: Is this the same as gravitational force?
A: It's expressed as multiples of Earth's gravity (1 g = 9.8 m/s²), but is actually centrifugal acceleration.

Q5: What's the maximum safe g-force?
A: Depends on the application - human tolerance is about 5-10 g, while industrial equipment may handle thousands of g.
