Notion vs Obsidian: Which Workspace Fits Your Notes?

Notion and Obsidian are both powerful note-taking apps, but they serve different needs: Notion is an all-in-one workspace with databases and rich formatting, while Obsidian is a local-first, plain-text system built around linked notes and privacy. Your choice depends on whether you prioritize collaboration and structure (Notion) or long-term ownership and speed (Obsidian).

Formula

The calculator works out your average pace and speed for a run, walk, or ride. Enter the time it took and the distance you covered; the tool returns your pace in minutes per kilometer and your speed in kilometers per hour. The formulas are:

• Pace (min/km) = Total time (min) ÷ Distance (km)
• Speed (km/h) = Distance (km) ÷ (Total time (min) ÷ 60)

Where t is the total time in minutes and d is the distance in kilometers. The pace tells you how many minutes each kilometer takes; the speed tells you how many kilometers you cover in one hour.

Worked Example

Using the default values from the calculator: you finish a 10 km run in 50 minutes.

1. Pace = 50 ÷ 10 = 5.00 min/km
2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

So your average pace is 5 minutes per kilometer, and your average speed is 12 kilometers per hour. The calculator shows the same results.

When to Use This Calculator

Use this tool to track training progress, plan race times, or compare efforts across different distances. For example, if you ran 5 km in 30 minutes, your pace is 6:00 min/km and your speed is 10 km/h. If you want to finish a half marathon (21.1 km) in 2 hours (120 minutes), your target pace is 120 ÷ 21.1 ≈ 5.69 min/km (about 5:41 per km). Enter different times and distances to see how pace and speed change.

How to Read the Results

A lower pace (min/km) means you are faster. A higher speed (km/h) also means you are faster. The two numbers are inversely related: if pace decreases, speed increases. For example, 4:30 min/km equals about 13.3 km/h, while 6:00 min/km equals 10 km/h. Use pace for planning workouts (e.g., “run at 5:30 pace�) and speed for quick comparisons.

Common Mistakes and Unit Mix-ups

The most frequent error is entering time in hours instead of minutes. If you run 1 hour 15 minutes, enter 75, not 1.15. Another mistake is mixing miles and kilometers. If your distance is in miles, convert to kilometers first (1 mile = 1.60934 km) or use a separate mile-based calculator. Also, remember that the pace result is in minutes per kilometer, not minutes per mile. For a 10-mile run in 80 minutes, the pace in min/km is 80 ÷ 16.09 ≈ 4.97, not 8.0.

Limits of the Formula

This calculator assumes a constant speed over the entire distance. Real-world runs have hills, stops, and changes in effort, so your actual pace varies. It also ignores factors like terrain, weather, and fatigue. For interval training or trail runs, the average pace may not reflect how hard you worked. Use the result as a simple average, not a precise measure of effort.

Frequently Asked Questions

How do I convert my pace from min/km to min/mile?
Multiply the min/km pace by 1.60934. For example, 5:00 min/km becomes 5 × 1.60934 ≈ 8:03 per mile.

What is a good running pace for a beginner?
It varies by age, fitness, and experience. A common conversational pace for a new runner is around 7:00–9:00 min/km (11–13 km/h). Focus on effort, not a specific number.

Can I use this for walking or cycling?
Yes. The formula works for any activity where you measure time and distance. For cycling, you might prefer speed in km/h directly.

How do I calculate my pace if I only know my speed?
Divide 60 by your speed in km/h. For example, if you run at 12 km/h, your pace is 60 ÷ 12 = 5 min/km.

Does the calculator account for elevation gain?
No. It only uses time and distance. Elevation gain affects effort but not the average pace calculation.
