To convert feet to miles, divide by 5280 (1 mile = 5280 feet). To convert hours to miles per hour, divide distance in miles by time in hours. Thus, to convert 30000 feet to miles per hour, first convert feet to miles (30000/5280), then divide by the number of hours to get miles per hour.
Meters per hour x 0.000621 = miles per hour.
To convert miles to kilometers, multiply by 1.6. The same if you want to convert miles/hour to kilometers/hour.
To convert kilometers per hour to miles per hour, you can multiply by 0.6214. Therefore, 130 km/hr is equal to approximately 80.78 miles per hour.
To convert 4.9 knots to miles per hour, you can multiply by 1.15078. Therefore, 4.9 knots is equal to approximately 5.64 miles per hour.
48.28kph
Divide km per hour by 1.609
To convert miles per hour to feet per second multiply by 5280 (feet in a mile) and then divide by 3600 (seconds in an hour).
To convert miles per hour to kilometers per hour, multiply by 1.60934. Therefore, 80 miles per hour is equivalent to approximately 128.75 kilometers per hour.
To convert speed change from miles per hour per second to miles per hour squared, you would need to divide by a time unit, which in this case would be seconds. Therefore, 3.6 miles per hour per second is equivalent to 3.6 miles per hour squared.
Miles per hour x 1.467 = feet per second.
Multiply by 3600.
