Free Software to Resize Partition: Safe Tools

Yes, there is reliable free software to resize partitions. The best options are the open-source GParted Live for desktop PCs and the built-in Disk Management tool in Windows, which is free and already on your system. This article explains how these tools work, how to choose between them, and how to resize a partition safely without losing data.

Formula

The calculator works out your average pace and speed for a run, walk, or bike ride. You enter the finish time in minutes and the distance in kilometers. The formulas are:

• Average pace (min/km) = Finish time (min) ÷ Distance (km)
• Average speed (km/h) = Distance (km) ÷ (Finish time (min) ÷ 60)

Where Finish time is in minutes, Distance is in kilometers, Average pace is in minutes per kilometer, and Average speed is in kilometers per hour. If you prefer miles, convert the distance to kilometers first (1 mile = 1.60934 km).

Worked Example

Using the default values: finish time = 50 minutes, distance = 10 km.

1. Average pace = 50 ÷ 10 = 5.00 min/km
2. Average speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator shows an average pace of 5.00 min/km and an average speed of 12.00 km/h for those inputs.

How to Read the Result

A lower pace (e.g., 4:30 min/km) means faster running; a higher pace (e.g., 7:00 min/km) means slower. Speed is the direct opposite: higher km/h is faster. For walking, a typical pace is 10–15 min/km; for running, 4–7 min/km. Use pace to plan training intervals, and use speed to compare with treadmill settings or bike computers.

Common Mistakes

• Mixing units: entering time in hours instead of minutes (e.g., 1.5 instead of 90) will give a wrong pace. Always convert hours to minutes (1 hour = 60 min).
• Forgetting to convert miles to kilometers. If your distance is in miles, multiply by 1.60934 before entering.
• Rounding too early: if you round the time or distance before dividing, the final pace can be off by several seconds. Keep full precision until the end.

Limitations of the Formula

The formula assumes a constant speed over the whole distance. Real runs have hills, stops, and changes in pace, so the average pace is just that—an average. It does not account for elevation gain, terrain, or wind. For intervals, you need a GPS watch or app that records per-kilometer splits.

When to Use This Calculator

Use it after a workout to see your average pace and speed, or before a race to estimate what time you need for a target pace. It is also handy for setting treadmill speed: if you know your target pace (e.g., 5 min/km), you can compute the speed (12 km/h) and set the treadmill accordingly. For cycling, it works the same, but note that bike speed is often higher, so the pace will be lower (e.g., 3 min/km).

Frequently Asked Questions

How do I convert my time from hours and minutes to minutes?

Multiply the hours by 60 and add the minutes. For example, 1 hour 15 minutes = 1×60 + 15 = 75 minutes. Enter 75 in the finish time field.

What if I ran 5 miles in 40 minutes? What is my pace?

First convert miles to kilometers: 5 miles × 1.60934 = 8.0467 km. Then enter 40 minutes and 8.0467 km. The calculator gives a pace of 4.97 min/km (about 4:58 per km) and a speed of 12.07 km/h.

Is a lower pace always better?

Yes, for running or walking, a lower pace means you are covering each kilometer faster. But “better� depends on your goal—for a long easy run, a slower pace is often appropriate. Compare your pace to your personal best or target.

Can I use this for swimming or rowing?

Yes, as long as you have a distance and a time. For swimming, you might use meters instead of kilometers—just convert distance to km (e.g., 1500 m = 1.5 km). The pace will be in min/km, which is less common for swimming, but the speed in km/h is still useful.

Why is my speed so high when I walk?

Walking speed is typically 4–6 km/h, so a pace of 10–15 min/km is normal. If you see a speed above 8 km/h, you are probably running or jogging. Check that you entered the time in minutes, not seconds.
