1. What is Pace Conversion?

Pace conversion between kilometers and miles is essential for runners comparing race performances or training plans that use different measurement systems. The half marathon distance is 21.0975 km or 13.1094 miles.

2. How Does the Calculator Work?

The calculator uses the pace conversion formula:

Where:

• \( P_{mile} \) — Pace in minutes per mile
• \( P_{km} \) — Pace in minutes per kilometer
• 1.60934 — Conversion factor (km to mile)

Explanation: Since 1 mile equals 1.60934 kilometers, running at the same speed will require more time per mile than per kilometer.

3. Importance of Pace Conversion

Details: Accurate pace conversion helps runners compare performances across different race distances and measurement systems, and adapt training plans designed in different units.

4. Using the Calculator

Tips: Enter your pace in minutes per kilometer (e.g., 5:30 min/km would be entered as 5.5). The calculator will show the equivalent pace in minutes per mile.

5. Frequently Asked Questions (FAQ)

Q1: Why is mile pace slower than kilometer pace?
A: Because a mile is longer than a kilometer (1 mile = 1.60934 km), so covering the same speed takes more time per mile.

Q2: How do I convert race times between km and miles?
A: Multiply your km pace by 1.60934 to get mile pace, or divide mile pace by 1.60934 to get km pace.

Q3: What's a good half marathon pace?
A: This varies by fitness level. Elite runners may maintain 3:00 min/km (4:50 min/mile), while beginners might aim for 6:30 min/km (10:28 min/mile).

Q4: Does temperature affect pace conversion?
A: No, the conversion is mathematical. However, environmental factors affect actual running performance.

Q5: Can I use this for full marathon pace?
A: Yes, the conversion factor is the same regardless of distance.
