Essential Space by Nothing: Still Free?

Essential Space by Nothing is a cloud storage feature bundled with Nothing phones, and as of now, it remains free for users. You get a set amount of storage at no cost, and you can use it to back up photos, videos, and other files directly from your device. This article explains exactly how it works, what the current limits are, and what you should know before relying on it.

Formula

The calculator above works out your average running pace and speed. The formula for pace is:

Pace (min/km) = Total time (minutes) ÷ Distance (km)

For speed:

Speed (km/h) = Distance (km) ÷ (Total time (minutes) ÷ 60)

Where:

• t = total time in minutes (e.g., 50 minutes)
• d = distance in kilometers (e.g., 10 km)
• Pace = minutes per kilometer, the standard way runners measure speed
• Speed = kilometers per hour, useful for comparing with cycling or driving

Worked Example

Using the default values: you run 10 km in 50 minutes.

1. Pace = 50 ÷ 10 = 5.0 min/km
2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.0 km/h

So your average pace is 5 minutes per kilometer, and your average speed is 12 km/h.

When to Use This Calculator

Use this pace calculator whenever you want to know your average speed for a run, walk, or cycle. It is especially helpful for:

• Planning training sessions – if you want to run 5 km in 30 minutes, what pace do you need? (Answer: 6 min/km)
• Comparing workouts – was your run faster than last week?
• Estimating finish times – if you hold a steady pace, how long will a longer distance take?

The result is an average, not a real-time measurement. Your actual pace will vary with hills, wind, and fatigue.

How to Read the Result

A lower pace (min/km) means faster running. For example, 4:30 min/km is faster than 5:00 min/km. Speed in km/h is higher when you are faster. Most runners think in pace, while cyclists and drivers think in speed. Convert between them easily:

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

For US users, you might want miles per hour or minutes per mile. To convert from km to miles, multiply kilometers by 0.621371. So 10 km = 6.21 miles. Your pace in min/mile = pace in min/km × 1.60934.

Common Mistakes and Unit Mix-Ups

The most common error is mixing minutes and hours. If you run for 1 hour 30 minutes, you must enter 90 minutes, not 1.5. Another mistake is using miles with kilometers. Always check your distance unit. If you measure distance in miles, convert to km first (miles × 1.60934) or use a separate calculator. Also, be careful with rounding: a pace of 5.33 min/km is not the same as 5:33 min/km. The calculator shows decimal minutes, so 5.33 means 5 minutes and 20 seconds (0.33 × 60 = 20 seconds). For exact time, multiply the decimal part by 60.

Limits of the Formula

The formula assumes constant speed. In reality, you speed up and slow down. For interval training or hilly routes, the average pace may not reflect your effort. Also, the calculator does not account for rest stops or traffic lights. For treadmill runs, the distance is usually accurate, but outdoor GPS can be slightly off. Always use the same method for consistent comparisons.

Frequently Asked Questions

How do I convert pace to speed?

Divide 60 by your pace in minutes per kilometer. For example, 5 min/km → 60 ÷ 5 = 12 km/h. For minutes per mile, divide 60 by that pace to get mph.

What is a good running pace for a beginner?

A comfortable jogging pace for a beginner is often between 6:00 and 7:30 min/km (about 9.7 to 8 km/h). It varies widely with age, fitness, and experience. The best pace is one you can maintain while holding a conversation.

How do I calculate my pace for a marathon?

Decide your target finish time in minutes, then divide by the marathon distance (42.195 km). For example, 4 hours = 240 minutes. 240 ÷ 42.195 = 5.69 min/km (about 5:41 per km). Use a pace calculator to check.

Why is my GPS pace different from my treadmill pace?

GPS measures your movement over the ground, including slight deviations, while treadmills measure the belt speed. Treadmills often read slightly faster or slower than actual outdoor pace. Calibrate your treadmill or use a footpod for accuracy.

Does elevation gain affect pace?

Yes. Running uphill slows you down, and running downhill speeds you up. The average pace formula does not include elevation. For hilly routes, your average pace will be slower than on flat ground, even if you run the same effort.

Can I use this calculator for walking?

Absolutely. Walking pace is usually between 10 and 15 min/km. Enter your time and distance to see your average walking speed.
