Magic Write in Canva Docs: What It Is & How to Use It

Magic Write is Canva Docs’ built-in AI text generator. You type a prompt or select a block of text, and it produces new sentences, paragraphs, or lists based on your request. It’s designed for anyone creating documents, presentations, or social media content directly in Canva, and it works best when you give it clear, specific instructions.

Formula

The core formula for pace and speed is straightforward:

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

Where:

• t = finish time in minutes (e.g., 50 minutes)
• d = distance in kilometers (e.g., 10 km)

The first formula gives you the average minutes per kilometer. The second converts that into kilometers per hour, which is the standard speed unit for running and cycling.

Worked Example

Using the default values from the calculator above:

1. Finish time = 50 minutes, Distance = 10 km.
2. Pace = 50 ÷ 10 = 5.00 min/km.
3. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h.

So a 50-minute 10K means you averaged 5 minutes per kilometer, which is exactly 12 km/h.

When to Use This Calculator

Use this calculator whenever you have a finish time and a distance and want to know your average pace or speed. Common situations:

• Training runs: You ran 8 km in 40 minutes – what was your pace?
• Race planning: You want to finish a half marathon (21.1 km) in 1 hour 45 minutes – what pace do you need?
• Cycling commutes: You rode 15 km in 45 minutes – what was your average speed?

The result is your average pace or speed. You likely didn’t run every kilometer at exactly the same pace – hills, stops, and fatigue all cause variation. But the average tells you if you’re on track for a goal.

How to Read the Result

Pace (min/km) is the number of minutes it takes you to cover one kilometer. A lower number means faster. For example, 4.5 min/km is faster than 6.0 min/km. In the US, runners often use minutes per mile; to convert, multiply the min/km value by 1.609.

Speed (km/h) is how many kilometers you cover in one hour. A higher number means faster. For running, 10 km/h is a common recreational pace; 15 km/h is very fast. For cycling, 25–30 km/h is typical for a fit rider on flat ground.

Common Mistakes & Unit Mix-Ups

• Mixing miles and kilometers: The calculator assumes both inputs are in kilometers. If your distance is in miles, convert to km first (1 mile = 1.609 km) or use a miles-based calculator.
• Using seconds instead of minutes: If you enter 50 seconds instead of 50 minutes, the pace will be absurdly fast. Always convert your time to minutes.
• Rounding too early: If you round the pace to 5.0 min/km and then compute speed from that rounded value, you’ll get a slightly different result. Let the calculator do the full calculation.

Also note that this calculator gives you average pace, not the pace you need to run each individual kilometer. In a race, you might run the first kilometer faster and the last slower, but the average is what matters for finishing time.

Limits of the Formula

The formula assumes constant speed. Real-world factors that affect your actual pace include:

• Elevation gain: Uphill sections slow you down.
• Weather: Wind and heat affect performance.
• Terrain: Trail running is slower than road running.
• Stops: Traffic lights, water breaks, and walk breaks add time.

For a more accurate race prediction, you’d need a more complex model that accounts for these factors, but for most training and planning purposes, the simple average is sufficient.

Frequently Asked Questions

How do I convert pace from min/km to min/mile?
Multiply the min/km value by 1.609. For example, 5.0 min/km × 1.609 = 8.05 min/mile. So a 5:00 min/km pace is roughly an 8:03 min/mile pace.

What is a good running pace for a beginner?
For a beginner, a comfortable pace is often around 7–8 min/km (11–13 min/mile). This is slow enough to hold a conversation. As fitness improves, pace naturally increases.

Can I use this for walking or cycling?
Yes. The formula works for any activity where you cover a distance over time. For walking, typical paces are 10–15 min/km. For cycling, speeds are usually 15–30 km/h, so pace in min/km would be 2–4.

How do I calculate my finish time if I know my pace?
Finish time (minutes) = pace (min/km) × distance (km). For example, at 5.5 min/km for 10 km, your finish time would be 55 minutes.

Why does the calculator show pace in min/km and not min/mile?
The calculator uses metric units because the formula and defaults are set to kilometers. If you need min/mile, you can either convert your distance to miles and use a different calculator, or convert the result manually as described above.
