Subject: BS: That's a lot of water!
Heard this on the telly the other day and didn't believe it so I worked it out.
one acre = 4046.8564224 square metres. one inch of rain = 0.0254 metres of rain so one inch of rain over one acre is 102.79 cubic metres of water so one inch of rain over a square mile is 102.79 x 640 = 65,785.7 cubic metres of water which is about 65,786 tonnes of water.
