📖 Overview
Use this tool to compare shorter high-intensity jump rope blocks.
⚙️ How It Works
This estimates calories burned from body weight and active minutes using a fixed intensity factor.
The Formula
Calories = Weight (kg) × Duration (min) × MET × 0.0175
| Weight | Body weight in kilograms |
| Duration | Active exercise time in minutes |
| MET | Metabolic Equivalent — intensity multiplier for the activity |
| 0.0175 | Unit conversion constant |
💡Calorie estimates can vary ±20% based on fitness level, technique, and individual metabolic rate. Use for directional planning, not precise nutrition tracking.
Quick Reference
| Activity | MET | 70 kg / 30 min | 80 kg / 30 min |
|---|---|---|---|
| Walking (moderate) | 3.5 | 128 kcal | 147 kcal |
| Cycling (leisure) | 6.0 | 220 kcal | 252 kcal |
| Running (8 km/h) | 8.0 | 294 kcal | 336 kcal |
| Swimming (laps) | 7.0 | 257 kcal | 294 kcal |
| HIIT | 10.0 | 367 kcal | 420 kcal |
Practical Tips
💡 Treat values as estimates, not exact measurements.
💡 Use consistent activity assumptions when comparing sessions.
💡 Track weekly totals to guide load progression.
Frequently Asked Questions
❓ Why is this not exact?
Actual burn varies by fitness level, effort, and physiology.
❓ Can I compare workouts with it?
Yes, it is useful for directional comparison under similar assumptions.
