I don't think there is a Thai translation of "reasonable". Better to estimate the mm/h/Sq.m of the worst month and divide it by the numbers of day in that month x 24.Originally Posted by Wasp
Anywhere in thailand has "TORRRENTIAL" rain, we had nearly one beer can full in just one day, your not in the Lake District drizzle now. I've found that for a typical 20 Chang beer cans long cement roof tile one needs to raise the top end by about 1 Chang beer can diameter.
I used to use mm and metre to measure, but now I'm more relaxed about accuracy, its all multiples of empty beer cans -length, diameter and volume.
