Ever wondered how many calories it takes to make a click of the mouse?

Does your work confine you in-front of a computer or laptop for the major part of the day? Worried about binge eating and lack of exercise that adds onto the trouble? Not sure about how many calories you end up spending at the end of the day? Well, there is some good news, you can at least count the number of calories spent to make a click on the mouse. PHP Science World recently published ‘convert anything to calories’ that includes calories burned through various human activities. It helps us scientifically assess the number of calories used when clicking a mouse. On an average a male burns 2550 calories while a female uses about 1940 calories. The excess calories left in the body isn’t very healthy and gets stored as fat. According to the author, “total volume of the muscles used to bend the index finger comes to be 10.8 cubic centimetres with a total weight of 11.7 grams.”

“On average, 16.7 micromoles of ATP (Adenosine tri-phosphate) are consumed in moving one gram of muscle for one second. So, the total amount of ATP burned to move 11.7 grams of muscle in the index finger is approximately 195 micromoles (11.7g×16.7μ mol/g). There are 7.3 calories in one mole of ATP energy, so the number of calories burned in clicking the mouse equals about 1.42 (7.3/1000) X 195).”

A little less than 1.42 Calories is all that is burnt to make a mouse click. That does not sound like bright news for sure; accommodating some time for daily calisthenics never fails and it is completely foolproof.
