How Calories Are Calculated
Your calculation step-by-step
The MET (Metabolic Equivalent of Task) value for sweeping floors is 3.3. This represents how many times more energy is used compared to resting.
Frequently Asked Questions
How are calories burned calculated?
Calories burned are calculated using the MET (Metabolic Equivalent of Task) formula: Calories = MET × weight(kg) × time(hours). MET values are sourced from the 2024 Compendium of Physical Activities, a peer-reviewed database maintained by Arizona State University researchers.
How many calories does sweeping floors burn?
A 70 kg person burns 115.5 calories sweeping floors for 30 minutes. The MET value for this activity is 3.3.
What is a MET value?
MET (Metabolic Equivalent of Task) represents the energy cost of an activity compared to rest. 1 MET equals resting metabolism (~3.5 mL O₂/kg/min). Walking is about 3.5 METs, running is 8-12 METs, and intense activities like swimming laps can be 10+ METs.
How many calories do I need to burn to lose weight?
To lose 1 pound (0.45 kg) of body fat, you need to burn approximately 3,500 calories more than you consume. According to CDC guidelines, a safe weight loss rate is 1-2 pounds per week, which requires a daily deficit of 500-1,000 calories through diet and exercise combined.
How accurate is this calorie calculator?
According to research in Medicine & Science in Sports & Exercise, MET-based calculations typically have an accuracy range of ±15-20% for most individuals. Factors like fitness level, body composition, and activity intensity can affect actual calorie burn. See our methodology section for details.
Scientific Methodology
Data Source: Compendium of Physical Activities
Our MET values are sourced from the 2024 Adult Compendium of Physical Activities, the gold-standard reference for energy expenditure research. This peer-reviewed database is maintained by researchers at Arizona State University and endorsed by the ACSM.
The MET Formula
We use the standard metabolic equation recommended by exercise physiologists:
Energy Expenditure Formula
This formula assumes a resting metabolic rate (RMR) of approximately 1 kcal/kg/hour, which is the baseline for all MET calculations.
Accuracy Considerations
According to research published in the Medicine & Science in Sports & Exercise, MET-based calculations typically have an accuracy range of ±15-20% for most individuals. Factors affecting accuracy include:
- Fitness level: Trained individuals may burn fewer calories for the same activity
- Body composition: Muscle mass affects metabolic rate
- Environmental factors: Temperature, humidity, and altitude can impact energy expenditure
- Technique: Movement efficiency varies between individuals
