One kilometre is equal to 1000 x 1000 = 1000000 millimetres. Therefore, 180 kilometres per second is equal to 180 x 1000000 = 180000000 millimetres per second.
There are 3600 seconds in one hour. Therefore, 180000000 millimetres per second is equal to 180000000 x 3600 = 648000000000 millimetres per hour.
There are 100000 millimetres in one kilometre. Therefore, 750000 millimetres per second is equal to 750000/1000000 = 0.75 kilometres per second. There are 3600 seconds in one hour. Therefore, 0.75 kilometres per second is equal to 0.75 x 3600 = 2700 kilometres per hour.
63 miles per second = 365,000 kilometers per hour.
There are 3600 seconds in one hour. Therefore, something travelling at 15000 millimetres per second is travelling at 15000 x 3600 = 54000000 millimetres per hour. There are 25.4 millimetres in one inch. Therefore, rounded to two decimal places, 54000000 millimetres per hour is equal to 54000000/25.4 = 2125984.25 inches per hour.
50 km/h is about 1,388.9 centimeters per second.
About 90 Kilometers.
There are 100000 millimetres in one kilometre. Therefore, 750000 millimetres per second is equal to 750000/1000000 = 0.75 kilometres per second. There are 3600 seconds in one hour. Therefore, 0.75 kilometres per second is equal to 0.75 x 3600 = 2700 kilometres per hour.
63 miles per second = 365,000 kilometers per hour.
There are 3600 seconds in one hour. Therefore, something travelling at 15000 millimetres per second is travelling at 15000 x 3600 = 54000000 millimetres per hour. There are 25.4 millimetres in one inch. Therefore, rounded to two decimal places, 54000000 millimetres per hour is equal to 54000000/25.4 = 2125984.25 inches per hour.
both are equal. 60 kilometer in a second=60X60X60 meters in an hour=60X60X60/1000 kilometers in an hour=216 kilometers in an hour.
There are 1,000 millimetres in a metre. There are 3,600 seconds in an hour. So to convert you need to multiply by 1,000 and again by 3,600. 100 metres per second = 100,000 millimetres per second. 100,000 millimetres per second = 3,600,000 millimetres per hour.
4 meters per second is equivalent to 14.4 kilometers per hour.
54 kilometers per hour is equal to 15 Meters per Second so 30 meters per second
50 km/h is about 1,388.9 centimeters per second.
Neither; they are equal.
The answer is follows: 750 000 millimetres per second is equal to 0,75 kilometres per second. There are 60 minutes in an hour and 60 seconds in each minute,therefore 0.75 km * 60 * 60 = 2 700 km/h
400 miles per hour is 586.7 feet per second or 643.74 kilometers per hour.
To convert 125 miles per hour to kilometers per second, you need to convert miles to kilometers and hours to seconds. 1 mile is approximately equal to 1.60934 kilometers, and 1 hour is equal to 3600 seconds. So, 125 miles per hour is equal to approximately 55.923 kilometers per second after conversion.
