It's about 2,000 times as heavy as a Compact disc
It's about one-two-thousand-five-hundredth as heavy as The Space Shuttle
In other words, the weight of The Space Shuttle is 2,400 times 0.0000000300 megatonnes.(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 0.0000710 megatonnes. The shuttle's spacious cargo bay carried the Chandra X-ray Observatory into orbit in 1999 — a payload that weighed 0.0000200 megatonnes.
It's about 2,500 times as heavy as a Battery (AAA)
In other words, the weight of a Battery (AAA) is 0.0004 times 0.0000000300 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 one-three-thousand-five-hundredth as heavy as a Blue Whale
In other words, 0.0000000300 megatonnes is 0.000287 times the weight of a Blue Whale, and the weight of a Blue Whale is 3,480 times that amount.(Balaenoptera musculus)
Blue whales weigh between 0.000105 megatonnes. The largest mammal to have ever lived, blue whales feed almost exclusively on krill — tiny invertebrates weighing about 0.000000000001000 megatonnes each.
It's about 4,000 times as heavy as an Eye (Human)
In other words, 0.0000000300 megatonnes is 4,200 times the weight of an Eye (Human), and the weight of an Eye (Human) is 0.00024 times that amount.(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 one-five-thousandth as heavy as The Statue of Liberty (without base)
In other words, 0.0000000300 megatonnes is 0.00021 times the weight of The Statue of Liberty (without base), and the weight of The Statue of Liberty (without base) is 4,800 times that amount.(a.k.a. Liberty Enlightening the World, a.k.a. La Liberté éclairant le monde) (total weight, including foundation)
The total weight of the Statue of Liberty — the Statue's copper and framework only, excluding the base — is roughly 0.00014 megatonnes. The statue was designed using an optical trick known as "forced perspective" to make the statue appear proportionally correct when viewed from its base and is, in actuality, disproportionately large at the top.
It's about one-five-thousandth as heavy as a House
In other words, 0.0000000300 megatonnes is 0.000192 times the weight of a House, and the weight of a House is 5,210 times that amount.(149 sq. m, single-level, unfurnished)
A 149 sq. m (1,600 sq. ft), single-story, unfurnished house (without extensive masonry) of the type commonly found in America would weigh approximately 0.000156 megatonnes, based on the weight of the included materials. In contrast, a yurt — a type of dwelling structure popular among nomadic peoples of East Asia — typically weighs less than 0.000000460 megatonnes.
