1. What is the Calories Burned Equation?

The calories burned equation estimates the number of calories expended during physical activity using MET (Metabolic Equivalent of Task), weight, and time. It provides a practical way to quantify energy expenditure for yard work and other activities.

2. How Does the Calculator Work?

The calculator uses the calories burned equation:

Where:

• \( \text{MET} \) — Metabolic Equivalent of Task (unitless)
• \( \text{weight} \) — Body weight in kilograms (kg)
• \( \text{time} \) — Duration of activity in hours

Explanation: The equation multiplies the MET value (which represents the intensity of the activity) by body weight and time to estimate total calories burned.

3. Importance of Calories Burned Calculation

Details: Calculating calories burned is essential for weight management, fitness tracking, and designing effective exercise programs. It helps individuals understand their energy expenditure during various activities.

4. Using the Calculator

Tips: Enter MET value (typically 3-6 for yard work), weight in kg, and time in hours. All values must be valid (MET > 0, weight > 0, time > 0).

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for yard work?
A: Yard work MET values typically range from 3.0-6.0, depending on intensity. Light gardening is around 3.0-4.0 METs, while heavy yard work can be 5.0-6.0 METs.

Q2: How accurate is this calculation?
A: This provides a reasonable estimate but individual variations in metabolism, efficiency, and intensity can affect actual calories burned.

Q3: Why use kg for weight instead of pounds?
A: The MET equation is standardized using metric units. To convert pounds to kg, divide by 2.2.

Q4: Can this calculator be used for women?
A: While the equation works for both genders, this calculator is specifically calibrated for men's metabolic rates.

Q5: How does intensity affect calories burned?
A: Higher intensity activities have higher MET values, resulting in more calories burned per hour for the same weight.
