MET Values for Treadmill Speeds: Complete Guide
Complete guide to treadmill MET values for walking and running. Learn how METs determine calorie burn and how our calculator uses them for accuracy.
MET values are the foundation of accurate calorie calculations for treadmill exercise. Understanding treadmill MET values helps you grasp why different speeds and inclines burn different amounts of energy—and why our Treadmill Calorie Calculator produces reliable results.
This guide covers everything about METs walking running treadmill activities, including complete conversion tables and how incline affects these values.
What Are MET Values?
MET stands for Metabolic Equivalent of Task. It represents the energy cost of an activity relative to rest.
- 1 MET = Energy expended while sitting quietly
- 1 MET ≈ 1 kcal/kg/hour (or 3.5 ml O₂/kg/min)
When an activity has a MET of 5, it means you're burning 5 times more energy than at rest. A MET of 10 means 10 times more energy.
MET Categories
| MET Range | Intensity Level | Examples |
|---|---|---|
| 1.0-1.5 | Sedentary | Sitting, lying down |
| 1.6-2.9 | Light | Standing, slow walking |
| 3.0-5.9 | Moderate | Brisk walking, light cycling |
| 6.0-8.9 | Vigorous | Jogging, swimming laps |
| 9.0+ | Very Vigorous | Running, competitive sports |
Most treadmill activities fall between 2.5 and 14 METs, depending on speed and incline.
Complete Treadmill MET Table: Walking Speeds
Here are the MET values for walking on a treadmill at various speeds (0% incline):
| Speed (mph) | Speed (km/h) | MET Value | Intensity |
|---|---|---|---|
| 1.0 | 1.6 | 2.0 | Light |
| 1.5 | 2.4 | 2.0 | Light |
| 2.0 | 3.2 | 2.0 | Light |
| 2.5 | 4.0 | 2.8 | Light |
| 3.0 | 4.8 | 3.4 | Moderate |
| 3.5 | 5.6 | 4.1 | Moderate |
| 4.0 | 6.4 | 4.7 | Moderate |
| 4.3 | 7.0 | 5.2 | Moderate |
Based on the formula: MET = 2.0 + (speed_kmh - 3) × 0.8, minimum 2.0
Complete Treadmill MET Table: Running Speeds
At higher speeds, the body transitions from walking to running, which changes the biomechanics and energy cost:
| Speed (mph) | Speed (km/h) | MET Value | Intensity |
|---|---|---|---|
| 4.5 | 7.2 | 5.7 | Vigorous |
| 5.0 | 8.0 | 6.5 | Vigorous |
| 5.5 | 8.9 | 7.5 | Vigorous |
| 6.0 | 9.7 | 8.4 | Vigorous |
| 6.5 | 10.5 | 9.3 | Very Vigorous |
| 7.0 | 11.3 | 10.1 | Very Vigorous |
| 7.5 | 12.1 | 10.9 | Very Vigorous |
| 8.0 | 12.9 | 11.7 | Very Vigorous |
| 8.5 | 13.7 | 12.5 | Very Vigorous |
| 9.0 | 14.5 | 13.3 | Very Vigorous |
| 10.0 | 16.1 | 14.9 | Very Vigorous |
Running speeds include additional adjustment: +0.5 MET per km/h above 7 km/h
How We Calculate Treadmill METs
Our Treadmill Calorie Calculator uses a dynamic MET formula that provides smooth transitions between walking and running:
The Formula
Base MET = 2.0 + (Speed in km/h - 3) × 0.8
If Speed > 7 km/h:
Add: (Speed - 7) × 0.5 per km/h
Minimum MET = 2.0
Why This Formula Works
- Baseline of 2.0 - Accounts for the basic metabolic cost of standing and moving
- Linear scaling (0.8 per km/h) - Reflects the increasing energy cost with speed
- Running adjustment - Captures the extra energy required for the running gait
- Smooth transition - No sudden jumps at the walk/run threshold
MET Values With Incline
Incline dramatically increases MET values. Add 0.2 MET for each 1% of incline:
Walking at 5 km/h (3.1 mph)
| Incline | MET Adjustment | Total MET |
|---|---|---|
| 0% | 0 | 3.6 |
| 3% | +0.6 | 4.2 |
| 5% | +1.0 | 4.6 |
| 8% | +1.6 | 5.2 |
| 10% | +2.0 | 5.6 |
| 12% | +2.4 | 6.0 |
| 15% | +3.0 | 6.6 |
Jogging at 8 km/h (5 mph)
| Incline | MET Adjustment | Total MET |
|---|---|---|
| 0% | 0 | 6.5 |
| 3% | +0.6 | 7.1 |
| 5% | +1.0 | 7.5 |
| 8% | +1.6 | 8.1 |
| 10% | +2.0 | 8.5 |
| 12% | +2.4 | 8.9 |
| 15% | +3.0 | 9.5 |
Running at 10 km/h (6.2 mph)
| Incline | MET Adjustment | Total MET |
|---|---|---|
| 0% | 0 | 9.1 |
| 3% | +0.6 | 9.7 |
| 5% | +1.0 | 10.1 |
| 8% | +1.6 | 10.7 |
| 10% | +2.0 | 11.1 |
| 12% | +2.4 | 11.5 |
| 15% | +3.0 | 12.1 |

The Walking-to-Running Transition
An important aspect of METs walking running treadmill is the transition between gaits. Around 7-8 km/h (4.3-5 mph), most people switch from walking to running.
Why Running Uses More Energy
At the same speed, running requires more energy than walking because:
- Vertical displacement - Running involves more up-and-down motion
- Flight phase - Both feet leave the ground, requiring more force to launch
- Impact absorption - Landing forces are 2.5-3x body weight vs 1-1.5x for walking
- Muscle recruitment - More muscle groups activate during running
The Crossover Point
Interestingly, at speeds around 8 km/h, running becomes more efficient than walking:
| Speed | Walking MET | Running MET | More Efficient |
|---|---|---|---|
| 6 km/h | 4.4 | N/A | Walking |
| 7 km/h | 5.2 | ~5.5 | Walking |
| 8 km/h | 6.0* | 6.5 | Similar |
| 9 km/h | 6.8* | 7.5 | Running |
*Theoretical walking values; most people cannot sustain walking at these speeds
Comparing Treadmill METs to Other Activities
How does treadmill exercise compare to other activities?
| Activity | MET Value | Equivalent Treadmill |
|---|---|---|
| Cycling (leisure) | 4.0 | Walking 3.5 mph |
| Swimming (moderate) | 6.0 | Jogging 5 mph |
| Elliptical (moderate) | 5.0 | Walking 4 mph |
| Jump rope (slow) | 8.8 | Running 6 mph |
| Rowing (moderate) | 7.0 | Jogging 5.5 mph |
| Stair climbing | 9.0 | Running 6.5 mph |
| HIIT training | 8-12 | Running 6-8 mph |
Treadmill running at 8+ mph is one of the highest MET activities available in a gym setting.
Using METs to Calculate Calories
Once you know the MET value, calculating calories is straightforward:
Calories = MET × Weight (kg) × Time (hours) × 1.05
Example 1: Walking
70 kg person, 5 km/h, 30 minutes, 0% incline
MET = 3.6
Time = 0.5 hours
Calories = 3.6 × 70 × 0.5 × 1.05 = 132 kcal
Example 2: Running
70 kg person, 10 km/h, 30 minutes, 0% incline
MET = 9.1
Time = 0.5 hours
Calories = 9.1 × 70 × 0.5 × 1.05 = 334 kcal
Example 3: Incline Walking
70 kg person, 5 km/h, 30 minutes, 12% incline
Base MET = 3.6
Incline bonus = 12 × 0.2 = 2.4
Total MET = 6.0
Time = 0.5 hours
Calories = 6.0 × 70 × 0.5 × 1.05 = 220 kcal
