Basically you can't, as the effort(the watts)needed to reach and maintain a certain speed depends on the riding conditions.
With a bit of a tailwind you might reach and maintain25 MPH/40 KMH easily oneday (=low power).
The next day, maybe there's a headwind instead, and you'll have to struggle like crazy(=high power)only to make 20 MPH/32 KMH.
You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.
13,500 kph
The conversion factor is 1.6 kilometers for each 1 mile.
1100 watts = 1.1 kilowatts. Generally, "kilo" is the standard prefix meaning multiply with 1000.
100 kph = 62.1 mph
299 KPH = 185.80 MPH
To convert kilometers per hour (kph) to miles per hour (mph), you can use the formula: 1 kph = 0.621371 mph. So, to convert kph to mph, you simply multiply the speed in kph by 0.621371.
To convert kilometers per hour (kph) to miles per hour (mph), you can multiply the speed in kph by 0.62137. For example, if a vehicle is traveling at 100 kph, it would be equivalent to approximately 62.14 mph.
Use this formula:m/sec x 3.6 = kph
It the unit is watts, megawatts is millions of watts, so to convert watts to megawatts, multiply the number of watts be 1,000,000.
Miles per hour can be converted to kilometers per minute by dealing with the individual units. Convert first to miles per minute by multiplying by 1/60. Then convert miles to kilometers by multiplying by 1. 609.
To convert calories to watts, you can use the formula: 1 calorie is equal to 0.001163 watts. Simply multiply the number of calories by 0.001163 to get the equivalent in watts.
Watts x 0.001341 = hp
kW x 1,000 = watts
Kilo means thousand. To convert from watts to kilowatts, divide the number of watts by 1000.
Watts are the product of amps x volts.
miles... in kph??? Anyway, the speed of light is 300,000 kilometers/second; you can convert that to whatever unit you want. For example, to convert to kilometers/hour, multiply by 3600.
