Knots vs miles per hr / temperature map

[sriram]

Regarding the wind gust map - as it is in knots - is this the same as mph

Its just that all media forecasts mention wind speeds mph - knots is more to do with boat and ship speed - so it would be good if this reflected these units

I guess the temp profile map is in degrees celsius - correct ?

Hi, could you link to the map you mean about please?  The GFS/NMM charts are in mph, and all temperatures are celsius, except if you select to view the actual forecasts themselves in fahrenheit.

To convert from knots to mph just add 15%.

A quick way is add 10%, and then add another half of that 10%.

For many years, it has been a problem attracting bright young people into science, technology and maths. And it cannot surprise, when we have SI units, that the young shake their heads at knots, mph, and dare I say it, Hpa.

 

Let's (k)not throw the baby out with the bathwater, but for heaven's sake, SI units really are superior to Imperial. I thought we had done away with old units ages ago.

it is the standard wind gust map on the extra subscription

That's in mph, no knot conversion needed :-)

Knots at sea .Conversion charts are available to print off or bookmark a site.  I use a chart showing 1-8 km/h in 1 column then 13- 20 in the other column on one A4 sheet.
