It's about 85,000 times as heavy as a Sesame Seed
In other words, 0.000000000310 megatonnes is 85,200 times the weight of a Sesame Seed, and the weight of a Sesame Seed is 0.00001170 times that amount.(Sesamum indicum)
A sesame seed weighs approximately 0.000000000000003640 megatonnes. The McDonald's Big Mac sandwich, which is well-known for its sesame seed top bun, accounts for the consumption of an estimated 0.000002010 megatonnes of sesame seeds each day.
It's about one-two-hundred-fifty-thousandth as heavy as The Space Shuttle
In other words, the weight of The Space Shuttle is 230,000 times 0.000000000310 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 one-three-hundred-fifty-thousandth as heavy as a Blue Whale
In other words, 0.000000000310 megatonnes is 0.000002970 times the weight of a Blue Whale, and the weight of a Blue Whale is 337,000 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 one-four-hundred-fifty-thousandth as heavy as The Statue of Liberty (without base)
In other words, the weight of The Statue of Liberty (without base) is 450,000 times 0.000000000310 megatonnes.(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 500,000 times as heavy as a Grain of Sugar
In other words, 0.000000000310 megatonnes is 496,000 times the weight of a Grain of Sugar, and the weight of a Grain of Sugar is 0.000002020 times that amount.(a.k.a. white sugar, a.k.a. white refined sugar, a.k.a. table sugar, a.k.a. sucrose, a.k.a. saccharose)
A grain of sugar weighs approximately 0.0000000000000006250 megatonnes. Sugar consumption varies widely by country; the average citizen of the United States consumes about 0.00000006120 megatonnes of sugar each year.
It's about one-five-hundred-thousandth as heavy as a House
In other words, 0.000000000310 megatonnes is 0.000001990 times the weight of a House, and the weight of a House is 503,000 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.
It's about 1,000,000 times as heavy as a Poppy Seed
In other words, the weight of a Poppy Seed is 0.000001000 times 0.000000000310 megatonnes.(Papaver somniferum)
Fifty percent oil by weight, a poppy seed weighs approximately 0.000000000000000300 megatonnes. The true pigment of a poppy seed is brown in color, while the characteristic bluish color is an optical illusion caused by a layer of calcium oxalate crystals refracting light rays.
