Unless you are training hard and seriously for a cycling race, triathlon or other event, this tool is really more of a luxury than a necessary workout aid. With the values from this BMI-Calculator you can check how much a change of body weight or height (or both) would influence the bicycle speed or the required propulsion power. This formula just needs basic arithmetic operations to determine the results. 2.80 is a constant used in both formulas. This is the equivalent of a 0.73% grade. This section of this page shows you the speed to watts conversion formula to convert values from speed to watts. It works in three different ways, based on: difference between velocities at two distinct points in time, distance traveled during acceleration, the mass of an accelerating object and the force that acts on it. The formulas used are: watts = 2.80/pace³; pace = ³√(2.80/watts) AC single phase watts to amps calculation. Power and Watts are interchangeable for this equation. The calculator is not applicable to DC charging stations, as DC fast charging works a bit differently. To do this, you need to estimate several parameters; reasonable defaults are given. Simply put, Virtual Watts is way to calculate how much wattage you're generating while suffering without having to invest in a bona fide power meter. Socialist seamates!
