Using transform file transform1:

FF = sprintf("%.1f", $x*1.9438)
NN = int($x*12.5 + .5)

and then executing bufrdump.pl on the same BUFR SYNOP file as in the previous example and with the same options except with --transform transform1 added, produced this output:

wmonr,FF,NN
01278,0.0,88
94120,14.0,13
94132,0.0,13
94150,11.1,63
94238,6.0,88
94326,11.1,100
94327,8.9,100
94462,15.9,13
95322,11.1,100
...

For ease of comparing, this was the previous output:

wmonr,FF,NN
01278,0.0,7
94120,7.2,1
94132,0.0,1
94150,5.7,5
94238,3.1,7
94326,5.7,8
94327,4.6,8
94462,8.2,1
95322,5.7,8
