It's about 35,000 times as heavy as a Nail
It's about one-forty-five-thousandth as heavy as a Tree (Sierra Redwood)
In other words, the weight of a Tree (Sierra Redwood) is 43,000 times 0.00000002950 megatonnes.(a.k.a. Giant Sequoia, a.k.a. Sierran redwood, a.k.a. Wellingtonia, a.k.a. "Big Tree", Sequoiadendron giganteum)
The weight of wood in a Giant Sequoia is 0.0013 megatonnes. General Sherman, a specimen in Sequoia National Park in Visalia, California, is the largest tree in the world by volume, with an estimated weight of about 0.0019 megatonnes.
It's about 100,000 times as heavy as a Raindrop
In other words, the weight of a Raindrop is 0.00001000 times 0.00000002950 megatonnes.(a.k.a. drop, a.k.a. droplet) (average)
The weight of a raindrop depends heavily on the type of weather, but averages about 0.000000000000200 megatonnes. The familiar teardrop shape of a raindrop is actually an optical illusion, caused by the reflection of the light and the motion of the drop.
It's about one-three-hundred-fifty-thousandth as heavy as The Eiffel Tower
In other words, 0.00000002950 megatonnes is 0.000002920 times the weight of The Eiffel Tower, and the weight of The Eiffel Tower is 342,000 times that amount.(a.k.a. La Tour Eiffel) (Paris, France) (total weight)
The Eiffel Tower weighs approximately 0.0101 megatonnes. Architected to be quickly assembled, the Tower contains only 930 cu. meters of solid material.
It's about one-four-hundred-fifty-thousandth as heavy as The Brooklyn Bridge
In other words, 0.00000002950 megatonnes is 0.0000022150 times the weight of The Brooklyn Bridge, and the weight of The Brooklyn Bridge is 451,500 times that amount.(a.k.a. New York and Brooklyn Bridge) (Manhattan and Brooklyn, New York City, New York) (total weight)
The total weight of the Brooklyn Bridge is approximately 0.01332 megatonnes. In a promotional event to prove the bridge's stability shortly after it opened, entertainer P. T. Barnum led a parade of 21 elephants across it in May of 1884.
It's about one-eight-hundred-fifty-thousandth as heavy as The Statue of Liberty
In other words, the weight of The Statue of Liberty is 833,000 times 0.00000002950 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, including her base is roughly 0.0246 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 1,500,000 times as heavy as a Grain of Rice
In other words, the weight of a Grain of Rice is 0.000000710 times 0.00000002950 megatonnes.(conventional; US; long-, medium-, and short-gran varieties; uncooked)
With great differences in variety, the average among a sampling of common short-, medium- and long-grain rices finds that a single grain weighs about 0.0000000000000210 megatonnes before cooking. A staple through most of human history, archaeological evidence indicates that the earliest rice cultivation was about 11,500 years ago.
