1. What is MET Conversion?

MET (Metabolic Equivalent of Task) is a unit that estimates the energy cost of physical activities. This calculator converts power output in watts to METs, which helps in comparing exercise intensity across different activities and individuals.

2. How Does the Calculator Work?

The calculator uses the MET conversion formula:

Where:

• \( Watts \) — Power output in watts
• \( Weight \) — Body weight in kilograms
• \( 3.5 \) — Conversion factor (mL O₂/kg/min per watt)
• \( +1 \) — Accounts for resting metabolic rate

Explanation: The formula converts mechanical power (watts) to metabolic equivalent by accounting for body weight and adding resting metabolic rate.

3. Importance of MET Calculation

Details: MET values help standardize exercise intensity measurements, allowing comparison across different activities and individuals. They're used in exercise prescription, research studies, and fitness tracking.

4. Using the Calculator

Tips: Enter power output in watts and body weight in kilograms. Both values must be positive numbers. The result is dimensionless (METs).

5. Frequently Asked Questions (FAQ)

Q1: What is a typical MET range for exercise?
A: Light activity: 1.6-3.0 METs, Moderate: 3.0-6.0 METs, Vigorous: >6.0 METs. Elite athletes can reach 15+ METs during intense exercise.

Q2: How accurate is this conversion?
A: It provides a reasonable estimate but individual variations in efficiency can cause ±10-20% differences from actual oxygen consumption.

Q3: Why include weight in the calculation?
A: Metabolic cost is proportional to body mass - heavier individuals expend more energy for the same power output.

Q4: Can I use this for cycling and rowing?
A: Yes, it works well for cycling and rowing ergometers. For other activities, direct MET measurements may be more accurate.

Q5: What's the relationship between watts and calories?
A: 1 watt = 0.01433 kcal/min (exact conversion). However, metabolic cost is typically 4-5× higher due to human inefficiency.
