It's about 1,000,000,000,000 times as heavy as a Quarter
In other words, 5.90 megatonnes is 1,041,000,000,000 times the weight of a Quarter, and the weight of a Quarter is 0.00000000000096060 times that amount.(United States quarter-dollar coin) (a.k.a. Quarter dollar, a.k.a. America the Beautiful quarter, a.k.a. two bits)
The America the Beautiful series quarters, which began to enter circulation in 2017, weigh 0.000000000005670 megatonnes each. In answer to the common riddle, there are 119 ridges around the edge of the coin in its current design.
It's about 850,000,000,000 times as heavy as an Eye (Human)
In other words, the weight of an Eye (Human) is 0.00000000000120 times 5.90 megatonnes.(adult)
A fully developed eye (in a person over the age of thirteen), weighs about 0.00000000000710 megatonnes. The pupil of the eye varies depending on the amount of light it is exposed to, but typically measures about 4 mm across.
It's about 500,000,000,000 times as heavy as a Battery (AAA)
In other words, the weight of a Battery (AAA) is 0.00000000000200 times 5.90 megatonnes.(Alkaline)
An "AAA" size battery weighs 0.0000000000120 megatonnes. Batteries are named by the American National Standards Institute (ANSI) Committee C18 and AAA batteries were given their name because they were smaller than the "AA" and "A" size batteries which were invented first.
It's about 400,000,000,000 times as heavy as a Compact disc
In other words, 5.90 megatonnes is 390,000,000,000 times the weight of a Compact disc, and the weight of a Compact disc is 0.00000000000260 times that amount.(a.k.a. CD)
A compact disc typically weighs 0.0000000000150 megatonnes. 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 300,000,000,000 times as heavy as a Mouse
In other words, 5.90 megatonnes is 280,000,000,000 times the weight of a Mouse, and the weight of a Mouse is 0.00000000000360 times that amount.(a.k.a. "House mouse", Mus musculus) (adult)
The weight of a mouse is typically an average of 0.0000000000210 megatonnes. 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 250,000,000,000 times as heavy as a Battery (AA)
In other words, the weight of a Battery (AA) is 0.00000000000400 times 5.90 megatonnes.(Alkaline)
An "AA" size battery weighs 0.0000000000240 megatonnes. 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.
It's about 150,000,000,000 times as heavy as a Light Bulb
In other words, the weight of a Light Bulb is 0.00000000000590 times 5.90 megatonnes.(a.k.a. lamp) (for A19-size, 60w, incandescent bulb by Bulbrite; package weight)
A standard, sixty-watt light bulb weighs about 0.0000000000340 megatonnes. The tightly-coiled filament inside a bulb of this size would measure about 579mm if uncoiled and stretched out.
