A (kilo)calorie is a unit of energy, while a watt is a unit of power, which describes the rate at which energy is expended. So a 100W bulb is using 100 joules a second. A kcal is about 4184 joules, so a 100W bulb takes about 42 seconds to consume (really: convert into light and heat) a kcal.
14 maj 2020 · All you need to know is the time spent cycling and the average power during that time, and you can get the energy burned using this general formula. Energy (Joules) = Power (Watts) * Time (Seconds) The problem is that you want to know your energy expenditure in kcal, not joules.
29 sie 2019 · energy (kcal) = avg power (Watts) X duration (hours) X 3.6 Using the formula above, we can see that a watt-hour (1 watt for 1 hour) is worth 3.6 kcal. So, let us say you commute at an average of 100W, every ten hours of commuting time will burn a pound of fat.
A calorie is the amount of energy required to raise one gram of water by 1 degree C (1 kelvin). However, this quantity depends on the atmospheric pressure and the starting temperature of the water. ... Thus the watt-hour is a unit of energy. An average human consumes energy at a rate of about 100 watts; the brain alone runs at about 5 watts. 1 ...
3 paź 2024 · Calculation Formula. To convert power in watts to calories burned over time, the following formula is used: \ [ \text {Calories} = \frac {\text {Power (Watts)} \times \text {Time (Seconds)}} {4.184} \] Where: Power is measured in watts (W) Time is measured in seconds (s) 1 calorie = 4.184 joules.
4 sie 2023 · Converting Watts to Calories Burned can be done using the formula: Calories Burned = Watts * Time in hours * 3.6. Watts represent the rate of energy expenditure, while calories measure the amount of energy.
10 maj 2024 · Calculate Calories: Click the calculate button to convert watts to calories using the conversion factor (1 watt = 0.239005736 calories per second). Interpret Results: The calculator will display the corresponding calorie value based on the input power. 10 FAQs About Watts To Calories Conversion.
