Useful Websites on the Internet? Top Picks

There is no single “best” website, but a handful of free, reliable sites cover most everyday needs—search, reference, maps, language, and file conversion. Below is a practical list of genuinely useful websites, grouped by what they do, with notes on how to get the most from each.

Formula

This calculator works out your average walking pace and speed. The formulas are:

Pace (min/km) = Time (minutes) ÷ Distance (km)

Speed (km/h) = Distance (km) ÷ (Time (minutes) ÷ 60)

Where:

• Time is the total walking time in minutes.
• Distance is the walked distance in kilometres.
• Pace is the number of minutes it takes to walk one kilometre.
• Speed is the number of kilometres you cover in one hour.

Worked Example

Using the default values: you walk 2.5 km in 30 minutes.

1. Pace = 30 ÷ 2.5 = 12.00 min/km
2. Speed = 2.5 ÷ (30 ÷ 60) = 2.5 ÷ 0.5 = 5.00 km/h

So your average pace is 12 minutes per kilometre, and your average speed is 5 kilometres per hour. That matches the calculator output above.

What This Tells You

Walking pace is a simple measure of how fast you move on foot. A pace of 12 min/km (5 km/h) is a typical brisk walk. Slower than 15 min/km is a gentle stroll; faster than 10 min/km is a very fast walk or almost jogging. The speed figure is useful if you want to estimate calories burned (roughly 300–400 kcal per hour for a 70 kg person at 5 km/h, but that varies with weight, terrain, and fitness).

Use this calculator when you plan a walking route, train for a charity walk, or just want to know your average speed after a hike. It also works for jogging or running if you enter the time and distance—the math is the same.

Common Mistakes

• Mixing units: If you measure distance in miles, convert to kilometres first (1 mile = 1.609 km). The calculator assumes kilometres.
• Using seconds instead of minutes: Enter total minutes, not hours and minutes. For example, 1 hour 15 minutes = 75 minutes, not 1.15.
• Rounding too early: Keep full precision until the final answer. Rounding 30 ÷ 2.5 to 12 is fine, but for other numbers, avoid rounding intermediate steps.

Limits of the Formula

The formula assumes a constant speed over the whole walk. In reality, terrain, stops, and weather change your pace. It also ignores the difference between walking on flat ground versus hills. For a hilly route, your average pace will be slower than on flat ground even if you work just as hard. The calculator gives an average, not a prediction of how fast you “should” go.

Also, the formula does not account for age, fitness, or health. It is a pure math tool, not a fitness assessment. If you are using walking for exercise and have health concerns, check with a doctor before starting a new routine.

Frequently Asked Questions

What is a good walking pace?
A brisk walking pace is about 5–6 km/h (10–12 min/km). For most adults, that means you are breathing harder but can still talk. Faster than 6 km/h is usually jogging for many people.

How do I measure my walking distance?
Use a phone app with GPS, a fitness tracker, or an online map that lets you draw your route. For a treadmill, the machine usually shows the distance. For outdoor walks, GPS is the most accurate.

Can I use this for running?
Yes. The same formula works for running pace (min/km) and speed (km/h). Runners often use pace in min/km or min/mile. If you use miles, convert the distance to kilometres first.

Why does my phone show a different pace?
Phone apps calculate pace in real time and may use a rolling average or account for pauses. Your average pace over the whole walk will differ from the instantaneous pace shown on the app. The calculator gives the overall average.

Does walking uphill change the pace?
Yes. Uphill sections slow you down, so your overall average pace will be slower than on flat ground. The calculator does not account for elevation gain, so treat the result as a flat-ground equivalent.

How many steps are in a kilometre?
For an average adult, about 1,200–1,500 steps per kilometre, depending on stride length. A shorter stride means more steps. This is not part of the pace formula, but it is a common follow-up question.
