It's about 0.000000000008 times as heavy as The Empire State Building.
In other words, 39 grains is 0.000000000007630 times the weight of The Empire State Building, and the weight of The Empire State Building is 131,000,000,000 times that amount.(New York City, New York)
The Empire State Building weighs approximately 5,110,000,000,000 grains. About 4% of the building's weight is its 6,000 cu. m (200,000 cu. ft) of limestone façade.
It's about 0.000000000003 times as heavy as The Golden Gate Bridge.
In other words, 39 grains is 0.000000000003140 times the weight of The Golden Gate Bridge, and the weight of The Golden Gate Bridge is 318,000,000,000 times that amount.(San Francisco, California and Marin County, California) (Post 1986 weight reduction; total weight of bridge, anchorage, and approaches)
Following the completion of the 1986 project to eliminate excess material, the total weight of the Golden Gate Bridge — including its anchorages and approaches — is 12,400,000,000,000 grains. The two main cables in the spanning the bridge are spun out of a total of 129,000 km (80,200 mi) of wire.
It's about 0.0000000000005 times as heavy as The Great Pyramid of Giza.
In other words, 39 grains is 0.000000000000430 times the weight of The Great Pyramid of Giza, and the weight of The Great Pyramid of Giza is 2,300,000,000,000 times that amount.(a.k.a. Pyramid of Khufu, a.k.a. Pyramid of Cheops) (Cairo, Egypt)
The Great Pyramid of Giza has an estimated mass of 91,000,000,000,000 grains. The 2,300,000 stones used in the construction of the pyramid weighed an average 35,000,000 grains and were quarried from distances of up to 805 km (500 mi) away.
It's about 0.000000000000000000000000000000002 times as heavy as The Sun.
In other words, 39 grains is 0.00000000000000000000000000000000130 times the weight of The Sun, and the weight of The Sun is 770,000,000,000,000,021,503,610,613,399,552.00000000000000000000000000000000000 times that amount.The sun has a mass of 31,000,000,000,000,001,757,761,616,363,586,060,288.0000000000000000000000000000000000000000 grains which represents 99.9% of the solar system's total mass. 98.7% of the sun's mass consists of hydrogen and helium — respectively the lightest and second-lightest elements in the universe.
It's about 0.0000000000000000000000000004 times as heavy as The Earth.
In other words, 39 grains is 0.000000000000000000000000000423050 times the weight of The Earth, and the weight of The Earth is 2,363,799,999,999,999,704,469,340,160.000000000000000000000000000000000 times that amount.The mass of the planet Earth is 92,186,999,999,999,991,788,106,416,128.0000000000000000000000000000000000 grains. The element iron makes up about 32% of that mass, or 29,591,999,999,999,999,542,183,329,792.0000000000000000000000000000000000 grains.
