1 kph = 0.621371192 mph so 42 kph = 42 * 0.621371192 = 26.097590064 mph
55 knots is approximately equivalent to 101.9 kilometers per hour (kph).
If you look on most speedometers (not all I'm sure) there is a second number above or below the main numbers on the speedo dial. The second set of numbers is the KPH. At about 62 MPH (if I remember right) is 100 KPH. So to answer your question I figure that 110 KPH is approximately 68 MPH, give or take.
230 km/h = 142.92 mph
0.8 kph is faster than 0.75 kph.
20 knots = 37.04 kph
300 knots = 555.6 kph or 345.2 mph
125 knots is equal to approximately 231 kilometers per hour.
1 kph = 0.621371192 mph so 42 kph = 42 * 0.621371192 = 26.097590064 mph
12 knots = 22.224 km/h
26 knots = 48.15 kph
55 knots is approximately equivalent to 101.9 kilometers per hour (kph).
24 knots = about 44.45 kph
55 knots = 101.86 kph
22 kph is approximately equal to 13.67 mph.
926 K/H
30 kph = 16.2 knots.
