Answer:
"The African elephant can be distinguished by its larger size and broader ears that drape over its shoulders. Males, or bulls, may reach 4 m (13 ft) in height and weigh 7000 kg (15,400 lb). Females, or cows, are shorter, averaging 2.8 m (9 ft) in height, and weigh considerably less, about 3600 kg (7900 lb).Asian elephants are shorter and stockier than their African relatives, with ears that do not reach their shoulders. The average Asian bull stands 3 m (10 ft) tall and weighs 2300 kg (5100 lb), about half the weight of male African elephants. Cows reach an average height of 2.4 m (7.8 ft) and weigh an average of 3000 kg (6600 lb)." 7000 kg

Redmond, Ian. Eyewitness: Elephant [amazon.com]. New York: Dorling-Kindersley, 2000. "The scientific name of the Asian elephant Elephas Maximus, means " biggest elephant," but it is only the second largest species of land animal. A bull (male) Asian elephant might weigh up to 11,900 lb (5,400 kg) and stand 10.5 ft (3.2 m) high at the shoulder. Cows (females) are smaller,weighing up to 9,171 lb (4,160 kg) and standing 8.3 ft (2.5 m) high." 5400 kg

Urquhart, Mary. Playground Physics: Physics terms. University of Colorado, 2001. "In one kilogram of peanuts (in the shell) there are about 370 individual peanuts. A single adult elephant can have a mass of about 1000 kilograms. That means that it would take about 370,000 peanuts to equal the mass of one elephant. So the mass of a single peanut is MUCH less than the mass of an elephant. If you wanted to gather enough elephants so that their combined mass equaled the mass of the Earth, you would need about 6,000,000,000,000,000,000,000 elephants! So the mass of a single elephant is MUCH MUCH less than the mass of the Earth, and the pull of gravity from one elephant (or even all living elephants grouped together) is too tiny to feel." 1000 kg
Life of an Elephant. Nature. PBS. "An adult male savannah elephant -- the largest land mammal in the world -- weighs about 12,000 pounds and stands roughly 10 feet tall at the shoulder. The smaller forest elephant weighs 10,000 pounds at most."
