However just for the hell of it I'll pretend this thread has a sane future. 15 Kilowatts = 15,000 Watts (exact result) Display result as. Is it me, or if this mystical chart existed and was reliable would we all be wasting our money on power meters, when we could just buy a cheap speedo? You missed the point. Here (kg) is the weight of the car plus passengers in kilograms (pounds divided by 2.2), V is the average speed of the car in meters per second (65 mph is 29.1 m/s), DV is the change in speed (10 mph is 4.47 m/s), Dt is the average time interval in seconds, and P is the power requirement in watts … flat course. This bike uses Panasonic 18650 Lithium Manganese cells (LiMn) which are considered the highest quality Lithium cells in the industry. 18 mph: 26 mph: Average Bike Speed up an 5% hill: 9.5 mph: 15 mph: Average Bike Speed up an 8% hill: 7 mph: 12 mph: Fastest Downhill Bike Speeds: 47 – 57 mph: 69 – 81 mph: Average sustainable watts for 1 hour (FTP) 200 watts: 415 watts: 5 second Sprint: 33mph/700 watts: 40mph/1250 watts: Tour De France Average Speed: N/A: 25mph (average of the 3 weeks) Let me put it another way. Watts is the SI unit of power. Ready, Set, Bike! Firstly, rewrite the initial watts to amps formula into the amps to watts equation: P = 3 * V * PH * I, As long as all of the values have desired units, simply input them into the formula: P = 3 * 100 V * 0.9 * 15 A = 4050 W, The outcome can be expressed as: "15 amps to watts, for the VLN equal to 100 volts is 4050 W." assume medium aerodynamic. watts = 1 × 15A × 120V = 1800W. 4 min recover. I need a chart with all other variables factored in except it taking. 1 watt is equal to 0.0013404053117582 HP.
