Using the conversion factor of 1 mph = 1.46 feet per second, 80 mph would be equivalent to: 117 feet per second When we talk about the speed of an object, we generally speak in the term of miles per hour (mph). Since accident sequences usually happen in seconds and feet, rather than hours and miles, it is easier to understand speeds effect on distance in feet per second (fps) than mph. The “magic” number for calculating mph into fps is to multiply mph by 1.466. The derivation of this is easy since there are 5280 feet in a mile and 3600 seconds in an hour. 5280 divided by 3600 equals 1.466. Therefore, a vehicle traveling at a rather mundane sounding 25 mph is actually moving at 36.65 feet per second (25x1.466=36.65). What this means in the real world can be explained as follows. At the point of possible perception of a hazard while traveling at 25 mph, using 3 seconds of perception/reaction time would mean that you would have traveled approximately 110 feet before any responsive action takes place (3x36.65=109.95). Add to this the distance necessary to stop an ATV traveling at 25 mph, which is about 42 feet, and you have traveled a total distance of approximately 152 feet.
80 mph converts to about 35.7632 meters per second.
Multiply by 1.47: 80 x 1.47 = 117.6 feet per second
128.74751999 kilometers per hour
Use this formula to convert knots to miles per hour: knots x 1.15 = mph25.3 knots x 1.15 = about 29.11 mph
1 knot is about 1.15 mph 20 knots = 23 mph you may try this online converter next time http://www.rillocenter.com/convert/speed.html
You can't convert between units of length (like kilometers) and units of speed (like miles/hour).
Since kilometers are bigger than miles, 60 km per hour would be faster
70 miles per hour is 112 kilometers per hour
You multiply mph by 1.60934. Therefore, 80 mph = 80 x 1.60934 = 129 (128.7472) km per hour.
80 mph = 128.75 km/h

I've gotten mine to about 80 mph i dont know how to convert it to kmh but the average 150rb will do about 70 to 75 mph
80 mph = 128.7 kph
80/1.6=50 MPH
80 km/h = 49.71 mph
80 mph = 128.75 kph
8 knots is about 9.2 mph.
80 mph for 1 hour will displace you 80 miles.
80 km/h = 49.70969538 mph
80 kph is 49.71 mph.
