The formula to estimate the calories burned while washing dishes is:
\[ \text{Calories Burned} = \frac{\text{MET} \times \text{Weight in kg} \times \text{Time in minutes}}{60} \]
Where:
The MET value represents the energy cost of physical activities as multiples of the resting metabolic rate. One MET is the rate of energy expenditure while at rest. A MET value of 1.8 for washing dishes indicates that this activity burns 1.8 times more calories than resting.
Example 1:
Using the formula:
\[ \text{Calories Burned} = \frac{1.8 \times 70 \times 30}{60} = 63 \, \text{kcal} \]
The calories burned are 63 kcal.
Example 2:
Using the formula:
\[ \text{Calories Burned} = \frac{1.8 \times 60 \times 45}{60} = 81 \, \text{kcal} \]
The calories burned are 81 kcal.
