The Climbers MET Calculator estimates calories burned during climbing activities using the standard metabolic equivalent (MET) formula. It covers rock climbing, stair climbing, hill hiking with a pack, and mountain-climber conditioning moves. Enter your body weight, session time, and match the effort profile, and the tool returns total calories, calories per minute, and a simple time-to-burn-100-kcal figure.
The calculator includes predefined MET profiles for common climbing scenarios and a custom MET field for advanced users who want to dial in an exact intensity. It automatically handles pounds/kilograms and minutes/hours, and displays a step-by-step breakdown of every calculation.
Designed for climbers, hikers, coaches, and fitness enthusiasts, this calculator helps you compare workouts, plan fuel for long climbing days, and better understand how body weight and intensity drive energy expenditure.

Your Body & Session
Step-by-Step Guide
Climbing energy expenditure is estimated with the standard metabolic equivalent formula:
- Choose a climbing profile that matches your effort. Each preset uses a MET value from established physical-activity compendiums.
- Enter your body weight in kilograms or pounds — the tool converts automatically.
- Enter session length in minutes or hours.
- Press Calculate Calories to see total kcal, calories per minute, and how long it takes to burn 100 kcal.
Quick-fill pills let you load common workouts and then adjust the numbers to your body weight.
How the MET Formula Works
One MET is the energy cost of sitting quietly: roughly 1 kcal per kilogram of body weight per hour. When you climb, your body works at several times that resting rate, so the MET value captures the intensity of the activity. Multiplying MET by body weight gives calories burned per hour; multiplying by actual time gives the session total.
Formula: kcal = MET × weight (kg) × duration (hours)
The MET values in this calculator are based on published compendium codes for rock climbing, stair climbing, hill hiking, and conditioning exercise such as mountain climbers. The Compendium of Physical Activities is a widely used reference for these intensity constants.
Worked Examples
Example 1 — 30-minute bouldering, 70 kg. Rock climbing, easy to moderate ≈ 5.8 MET. Calories = 5.8 × 70 × 0.5 = 203 kcal.
Example 2 — 20-minute vigorous stair stepper, 155 lb. Convert: 155 lb ÷ 2.20462 ≈ 70.3 kg. Time = 20 min ÷ 60 = 0.333 hr. MET ≈ 8.8. Calories = 8.8 × 70.3 × 0.333 ≈ 206 kcal.
Example 3 — 45-minute hill hike with a heavy pack, 80 kg. MET ≈ 8.3. Calories = 8.3 × 80 × 0.75 ≈ 498 kcal.
MET Reference Table
| Activity | MET value |
|---|---|
| Rock climbing — easy to moderate | 5.8 |
| Rock climbing — challenging | 8.0 |
| Stair climbing / stair stepper — moderate | 5.0 |
| Stair climbing / stair stepper — vigorous | 8.8 |
| Hill hiking / climbing hills, light pack | 6.0 |
| Hill hiking / climbing hills, heavy pack | 8.3 |
| Mountain climber exercise | 8.0 |
These values are representative averages. Your actual MET may differ based on age, fitness, terrain, rope technique, rest breaks, and how hard the session feels.
Common Mistakes to Avoid
- Forgetting unit conversion. The MET formula always works in kg and hours. The tool converts pounds and minutes for you, but if you adapt the formula elsewhere, convert first.
- Choosing too high a MET. A casual gym session is closer to 5–6 MET; an outdoor overhang burn may reach 8–9. Be honest about intensity.
- Counting rest time as climbing time. If your session includes long rests between routes, use the active time or choose a slightly lower MET profile.
Frequently Asked Questions
Is this calculator accurate for me? It gives a solid estimate for planning workouts and comparing activities. Individual metabolism, muscle mass, temperature, and skill all shift the exact number by roughly 10–20%.
Can I use it for training goals? Yes. Track calories per session, but combine MET-based estimates with perceived exertion and heart-rate data if you are trying to hit a precise energy target.
Where do the MET values come from? The profiles adapt values from the Compendium of Physical Activities, a research-based reference maintained by physical-activity scientists. The MET concept is also explained on Wikipedia.
