1. What is a Time Ratio Calculator?

Definition: This calculator computes the ratio between two time periods, showing their proportional relationship.

Purpose: It helps compare time durations in various applications like project planning, productivity analysis, and process optimization.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Time ratio (dimensionless)
• \( T_1 \) — First time period (hours)
• \( T_2 \) — Second time period (hours)

Explanation: The ratio shows how many times longer or shorter the first time period is compared to the second.

3. Importance of Time Ratio Calculation

Details: Time ratios are crucial for comparing process durations, measuring efficiency improvements, and analyzing performance metrics.

4. Using the Calculator

Tips: Enter both time values in hours. The calculator will show their ratio. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What does a ratio > 1 mean?
A: It means T₁ is longer than T₂. For example, 1.5 means T₁ is 1.5 times longer than T₂.

Q2: What does a ratio < 1 mean?
A: It means T₁ is shorter than T₂. For example, 0.75 means T₁ is 75% of T₂'s duration.

Q3: Can I use different time units?
A: The calculator uses hours, but you can use any unit as long as both times use the same unit.

Q4: How is this different from percentage?
A: A ratio shows the direct relationship, while percentage expresses the ratio as a fraction of 100.

Q5: What are common applications?
A: Comparing before/after process times, analyzing speed improvements, or evaluating time allocation between tasks.
