It's about twenty times as heavy as a Dalmatian
In other words, 680 kilograms is 23.10 times the weight of a Dalmatian, and the weight of a Dalmatian is 0.0433 times that amount.(a.k.a. Dalmatinac, a.k.a. Carriage Dog, a.k.a. Spotted Coach Dog, a.k.a. Firehouse Dog) (FCI standard; male)
The Fédération Cynologique Internationale (FCI) calls for Dalmatians to weigh between 27 and 32 kg.

It's about 55 times as heavy as a Gold Bar
In other words, 680 kilograms is 54.656269170 times the weight of a Gold Bar, and the weight of a Gold Bar is 0.01829616282 times that amount.(London Good Delivery bar)
A "London Good Delivery" gold bar — the variety commonly held by Central Banks — should weigh 12.44139072 kg (400 troy oz). The largest gold bar ever produced was minted by Mitsubishi Materials Corporation (a sibling company of the auto manufacturer) in 2005 and weighed 250 kg.
It's about 80 times as heavy as a Dachshund
In other words, the weight of a Dachshund is 0.01 times 680 kilograms.(a.k.a. "Wiener dog", a.k.a. Teckel, a.k.a. Dackel, a.k.a. "hot dog dog", a.k.a. "sausage dog", a.k.a. "doxie") (FCI standard; standard size)

It's about 100 times as heavy as a Bowling Ball
In other words, 680 kilograms is 99.94289220 times the weight of a Bowling Ball, and the weight of a Bowling Ball is 0.010005714 times that amount.(most common selection among male bowlers)
With an allowable range of 4.989516070 kilograms, the most-preferred bowling ball weight among adult, male bowlers is 6.803885550 kilograms. Because regulation balls measure the same diameter irrespective of their weight, ball density varies by size and balls weighing less than about 5 kg (11 lbs) will float in water.

It's about one-one-hundredth as heavy as The Space Shuttle
In other words, 680 kilograms is 0.0096 times the weight of The Space Shuttle, and the weight of The Space Shuttle is 100 times that amount.(for Endeavour, a.k.a. OV-105, a.k.a. Orbiter Vehicle-105) (empty weight, excluding main engines)
When empty, the space shuttle Endeavour weighs 71,000 kilograms. The shuttle's spacious cargo bay carried the Chandra X-ray Observatory into orbit in 1999 — a payload that weighed 19,737 kg.
