Well, let's think about this methodically. 1000kg to a ton. usually one square metre of water weighs 1kg. To be brutally honest, you answered your own question... "How much does a hundred tons of water weigh?"
100 tons...
1 ton is 20 cwt, so 100 ton is 2000 cwt
1 cwt is 8 st, so 2000 cwt (100 tons) is 16000 st
1 st is 14 lb, so 16000 st (100 tons) is 224000 lb
1 lb is approx 0.454kg, so 224000 lb (100 tons) is approx 101605 kg
1 tonne is 1000kg, so 100 tons is approx 101.605 tonnes.
