1. What is a Speed Increase Ratio Calculator?

Definition: This calculator determines the ratio between a new speed and an old speed, showing how much the speed has increased or decreased.

Purpose: It helps automotive enthusiasts, engineers, and drivers understand the relative change in vehicle speed.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Speed Ratio — Dimensionless ratio (e.g., 1.5 means 50% increase)
• New Speed — Final speed (meters per second, m/s)
• Old Speed — Initial speed (meters per second, m/s)

Explanation: A ratio greater than 1 indicates speed increase, while less than 1 indicates decrease.

3. Importance of Speed Ratio Calculation

Details: Understanding speed ratios helps in performance tuning, gear ratio selection, and analyzing vehicle modifications.

4. Using the Calculator

Tips: Enter both speeds in m/s (convert from km/h by dividing by 3.6). Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What does a speed ratio of 1.25 mean?
A: It means the new speed is 1.25 times (25% higher than) the old speed.

Q2: How do I convert km/h to m/s?
A: Divide km/h value by 3.6 (e.g., 100 km/h = 27.78 m/s).

Q3: Can I use this for RPM calculations?
A: Yes, the same ratio concept applies to rotational speeds.

Q4: What if my ratio is less than 1?
A: This indicates a speed reduction (e.g., 0.8 means 20% slower).

Q5: Does this account for acceleration time?
A: No, this only calculates the ratio between two speeds, not the time taken to change between them.
