To link to this speed and velocity – millimeter per second to kilometers per hour units converter, only cut and paste the following code into your html….

conversion result for two speed and velocity units:
From unit Symbol	Equals Result	To unit Symbol
1 millimeter per second mm/sec	= 0.0036	kilometers per hour km/h

Take your current speed in either kmph or mph. Divide it by 60 to get kilometers per minute or miles per minute. Divide by 60 again, getting kilometres per second or miles per second.

Convert 750 Kilometers per Hour to Miles per Hour

km/h	mph
750.00	466.03
750.05	466.06
750.10	466.09
750.15	466.12

I would say 4 min Per km for a recreational runner at close to 50 is very decent efforts. 4 minutes / 1 km = 4 minutes / 0.6214 miles = 6.4371 minutes per mile = 6:26 per mile. That would be a very fast running speed. The fastest I have ever run is 6:55 per mile for 1 mile, which is 4:18 per km for 1 km.

The biggest reasons the U.S. hasn’t adopted the metric system are simply time and money. When the Industrial Revolution began in the country, expensive manufacturing plants became a main source of American jobs and consumer products.

Myanmar and Liberia are the only other countries in the world that haven’t officially adopted the metric system yet. In both countries, metric measurements are used alongside imperial ones.

According to the U.S. Central Intelligence Agency’s online The World Factbook (2016), the only countries that have not adopted the metric system are Myanmar (also known as Burma), Liberia and the United States.

1 millimeter per second (mm/s) = 0.0036 kilometer per hour (kph).

Enter the speed in kilometers per hour below to get the value converted to kilometers per second….Kilometer Per Hour to Kilometer Per Second Conversion Table.

Kilometers Per Hour	Kilometers Per Second
1 km/h	0.000278 km/s
2 km/h	0.000556 km/s
3 km/h	0.000833 km/s
4 km/h	0.001111 km/s

0.0290 kilometers per second

If we convert 1 m/s to km/h, we get, 1 m/s = 3.6 km/h. Now, it is easy to compare 1 km/h and 3.6 km/h, which shows that 3.6 km/h is a faster speed. Hence, 1 m/s is faster than 1 km/h.

Please provide values below to convert kilometer/second [km/s] to meter/second [m/s], or vice versa….Kilometer/second to Meter/second Conversion Table.

Kilometer/second [km/s]	Meter/second [m/s]
1 km/s	1000 m/s
2 km/s	2000 m/s
3 km/s	3000 m/s
5 km/s	5000 m/s

Speed in kilometers per hour (km/h) Kilometers per hour is often used for car speeds. One hour at this speed moves you 100 km. Example: One minute at 60 km/h moves you 1 km.

Bolt ran 200 meters in 19.19 seconds, while a cheetah could sprint that distance in 6.9 seconds, a Black Caviar racehorse would gallop the same in 9.98 seconds, and a greyhound in 11.2 seconds.

Usain Bolt, the Jamaican 100-meter runner who holds the record as being the fastest human to have ever walked the surface of the earth, has an acceleration of between 8m/s2 and 10m/s2. What that means is that all factors held constant, Usain Bolt can outrun a car within the first 20 meters in a 100m race.

The fastest snake happens to be the black mamba. The black mamba can travel up to 12 mph in short bursts, which is faster than humans. Though speeds of this snake have sometimes been exaggerated in myths and legends, the average person could not outrun this snake once it has locked you in its sight.

Snakes can smell, they can do it better than dogs can. However, they are not as intelligent as dogs, and therefore- they CAN “smell your fear”, but they don’t understand what it means. However, depending on your body language, a snake may be able if you are intending on eating it or not.

A viral photo, most likely from Southeast Asia, shows a rarely seen encounter. A King Cobra (the worlds longest venomous snake) has attempted to catch, kill and eat this Reticulated Python (grows to be the longest snake in the world) and has been coiled and strangled by the python and died in the process.

In fact, there are well documented reports of king cobras feeding on the reticulated python in Southeast Asia. It is no doubt that king cobras do occasionally consume large prey such as monitor lizards or even pythons.

“There is no evidence that pythons are resistant to cobra venom, and the time that a snake takes to kill its prey will depend to a large extent on the amount of venom injected,” notes herpetologist and author Johan Marais. Cobra species in Africa also have a taste for their own kind.

To conclude, the king cobra is the most dangerous snake in the world, and it will easily win during the head to head fight. King Cobra can easily beat black mamba, but in some cases, the fight will go on for a long time because the black mamba will keep escaping from a king cobra.
