1. What is RPM to G Calculator?

Definition: This calculator converts rotational speed (RPM) and radius to relative centrifugal force (RCF or 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)
• 894 — Conversion factor combining unit conversions and gravitational acceleration

Explanation: The formula relates rotational speed to the equivalent gravitational force experienced at a given radius.

3. Importance of RPM to G Calculation

Details: Accurate G-force calculation ensures proper operation of centrifuges, safety in rotational equipment, and correct experimental conditions.

4. Using the Calculator

Tips: Enter the RPM (rotations per minute) and the rotational radius in centimeters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the radius measured in centimeters?
A: The formula uses centimeters because it's the standard unit in laboratory and industrial applications for this calculation.

Q2: What's a typical RPM range for centrifuges?
A: Laboratory centrifuges typically operate between 1,000-15,000 RPM, while ultracentrifuges can reach 100,000 RPM.

Q3: How does radius affect G-force?
A: G-force increases linearly with radius - doubling the radius doubles the G-force at the same RPM.

Q4: What's the relationship between RPM and G-force?
A: G-force increases with the square of RPM - doubling the RPM quadruples the G-force.

Q5: Where is this calculation used?
A: Centrifuge operation, industrial mixers, amusement park rides, and any application involving rotational motion.
