Dear All,
I have just been reading this blog at http://globonsomeday.blogspot.com/2009/07/improving-metric-system.html
where they say:
Another metric unit commonly encountered in everyday usage is the
unit of speed, kilometres per hour. The official SI base unit for time
is seconds, and therefore a more appropriate measurement of speed is
metres per second. For example, 100 km/h is equivalent to 27.78 m/s.
I wonder if we will ever be ready to embrace the idea of using the SI
unit, metres per second, for speed in everyday conversations.
Let's take the example given above with sensible rounding. The speed
limit on a highway might then become 25 metres per second.
Other limits might go like this (using Australian examples):
School zone 40 km/h 10 m/s
Suburban street 60 km/h 15 m/s
Main (4 lane) cross town road 70 km/h 20 m/s
Highway 100 km/h 25 m/s
Freeway 110 km/h 30 m/s
It might be interesting to see this idea applied to speed limits in
Asia, Europe, the UK and the USA.
Cheers,
