1. What is a Ratio Calculator?

Definition: This calculator determines the ratio between two numbers, showing their proportional relationship.

Purpose: It helps in various fields like mathematics, finance, engineering, and science to compare quantities and establish relationships.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A \) — First number (any unit)
• \( B \) — Second number (same unit as A)
• Ratio — Dimensionless quantity representing A relative to B

Explanation: The ratio is calculated by dividing the first number by the second number.

3. Importance of Ratio Calculation

Details: Ratios are fundamental in comparing quantities, analyzing proportions, making mixtures, financial analysis, and statistical measurements.

4. Using the Calculator

Tips: Enter both numbers in the same units. The second number must be greater than zero. Results are displayed with 6 decimal places for precision.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units for A and B?
A: No, both numbers should be in the same units for a meaningful ratio.

Q2: Why can't B be zero?
A: Division by zero is mathematically undefined and would produce an infinite ratio.

Q3: What does a ratio of 1 mean?
A: A ratio of 1 indicates that both quantities are equal (A = B).

Q4: How do I interpret a ratio less than 1?
A: A ratio < 1 means A is smaller than B. For example, 0.5 means A is half of B.

Q5: Can I calculate the inverse ratio?
A: Yes, simply swap the input values (put B first and A second).
