It's about 0.00000000000000002 times as big as an Halley's Comet
In other words, 0.0019 bushels is 0.0000000000000000170 times the size of an Halley's Comet, and the size of an Halley's Comet is 59,000,000,000,000,000.0000000000000000000 times that amount.(Comet Halley, officially "1P/Halley") (volume calculated based on 2005 dimensions)
Halley's Comet, the famous comet visible to observers on Earth approximately every 76 years, has a peanut- or potato-shaped nucleus made of rock, dust, ice, and various frozen gasses. The nucleus measures approximately 15 km by 8 km by 8 km, which yields a calculated volume of 110,000,000,000,000.00000000000000000 bushels. The coma of the Comet — the trail of sublimated gasses that give the Comet its visibility — may be up to 100,000 km in length.
It's about 0.00000000000000000000005 times as big as Earth's Oceans
In other words, 0.0019 bushels is 0.0000000000000000000000480 times the size of Earth's Oceans, and the size of Earth's Oceans is 20,999,999,999,999,997,902,848.0000000000000000000000000 times that amount.(Total water volume of Atlantic, Pacific, Indian, Arctic, and Southern Oceans) (estimated)
Over 97% of the Earth's water is found in the planet's five oceans for a total volume of about 40,000,000,000,000,000,000.0000000000000000000000 bushels. The Pacific Ocean is the largest ocean, covering 165,760,000 sq. km — more than double the area of the Atlantic Ocean at 82,400,000 sq. km.
It's about 0.00000000000000000003 times as big as The Gulf of Mexico
In other words, 0.0019 bushels is 0.000000000000000000027510 times the size of The Gulf of Mexico, and the size of The Gulf of Mexico is 36,350,000,000,000,000,000.000000000000000000000000 times that amount.(water volume)
The Gulf of Mexico contains 69,070,000,000,000,000.000000000000000000000 bushels of water. Every second, the Mississippi River empties 340,500 bushels of water into the Gulf.
It's about 0.00000000000000002 times as big as The Grand Canyon
In other words, 0.0019 bushels is 0.00000000000000001610 times the size of The Grand Canyon, and the size of The Grand Canyon is 62,100,000,000,000,000.00000000000000000000 times that amount.(Coconino County and Mohave Counties, Arizona, near Fredonia and Grand Canyon, Arizona)
A dynamic and continuously changing landscape, the Grand Canyon has an approximate volume of 118,000,000,000,000.000000000000000000 bushels. The strata of the rock visible in the Canyon's walls display nearly 2 billion years of geological history.
