It's about 30,000 times as heavy as a Raindrop
In other words, the weight of a Raindrop is 0.0000300 times 0.00000000500 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-thirty-thousandth as heavy as a House
In other words, 0.00000000500 megatonnes is 0.00003210 times the weight of a House, and the weight of a House is 31,200 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 one-one-hundred-fifty-thousandth as heavy as Christ the Redeemer (statue)
In other words, 0.00000000500 megatonnes is 0.000007870 times the weight of Christ the Redeemer (statue), and the weight of Christ the Redeemer (statue) is 127,000 times that amount.(a.k.a. O Cristo Redentor, a.k.a. Christo redemptor) (Rio de Janeiro, Brazil)
Christ the Redeemer weighs 0.000635 megatonnes. The statue overlooks the city of Rio de Janeiro from atop the 709.9-meter (2,329 ft) granite peak in the Tijuca Forest National Park.
It's about 250,000 times as heavy as a Grain of Rice
In other words, the weight of a Grain of Rice is 0.00000420 times 0.00000000500 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.
It's about one-two-hundred-fifty-thousandth as heavy as a Tree (Sierra Redwood)
In other words, the weight of a Tree (Sierra Redwood) is 260,000 times 0.00000000500 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 1,000,000 times as heavy as a Grain of Sand
In other words, 0.00000000500 megatonnes is 1,100,000 times the weight of a Grain of Sand, and the weight of a Grain of Sand is 0.000000910 times that amount.(medium grain)
With tremendous variety in the size of grain and the component material, grains of sand weigh an average of 0.00000000000000440 megatonnes. In 2007, a team of seven in Myrtle Beach created the world's tallest sandcastle, which measured 15.10 m (49.55 ft) in height.
It's about 1,500,000 times as heavy as a Sesame Seed
In other words, 0.00000000500 megatonnes is 1,370,000 times the weight of a Sesame Seed, and the weight of a Sesame Seed is 0.000000730 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.
