It's about one-twentieth as heavy as a Gold Bar.
In other words, 623.689508750 grams is 0.05013020833 times the weight of a Gold Bar, and the weight of a Gold Bar is 19.948051950 times that amount.(London Good Delivery bar)
A "London Good Delivery" gold bar — the variety commonly held by Central Banks — should weigh 12,441.390720 grams. The largest gold bar ever produced was minted by Mitsubishi Materials Corporation (a sibling company of the auto manufacturer) in 2005 and weighed 250,000 grams.
It's about thirty times as heavy as a Battery (AA).
In other words, the weight of a Battery (AA) is 0.038 times 623.689508750 grams.(Alkaline)
An "AA" size battery weighs 24 g. AA batteries came into common use during World War II and were given their name by the American National Standards Institute (ANSI) Committee C18 because they were smaller than the "A" size batteries which were invented first.

The weight of a mouse is typically an average of 12 to 30 g. While most mice typically live two to three years, the Methuselah Mouse Prize — an award administered by a non-profit organization which advances aging-related research — was once awarded to a team of scientists whose research resulted in a mouse living just under five years.
It's about 40 times as heavy as a Compact disc.
In other words, 623.689508750 grams is 42 times the weight of a Compact disc, and the weight of a Compact disc is 0.024 times that amount.(a.k.a. CD)
A compact disc typically weighs 15 g. Data is stored on CDs by encoding into the track a series of tiny pits — each between 3.5 and 850 µm (0.00014 and 0.033 in) in length.
It's about one-forty-fifth as heavy as a Dalmatian.
In other words, the weight of a Dalmatian is 47.40 times 623.689508750 grams.(a.k.a. Dalmatinac, a.k.a. Carriage Dog, a.k.a. Spotted Coach Dog, a.k.a. Firehouse Dog) (FCI standard; male)
