It's about one-two-hundred-fiftieth as big as Sydney Harbour
In other words, 164,174,800,000 tablespoons is 0.00432 times the size of Sydney Harbour, and the size of Sydney Harbour is 231 times that amount.(formally Port Jackson, a.k.a. Sydney Harbor) (Sydney, New South Wales, Australia) (total estuary water volume at high tide)
Lending the term "sydharb" or "sydarb" to comparable quantities of water, Sydney Harbor contains approximately 38,000,000,000,000 tablespoons of water. Snapper Island, a onetime naval facility loocated in the Harbour, was transformed by the dredging efforts of the Australian Navy from a 2,360 sq. m (25,400 sq. ft) outcropping to a 16,500 sq. m (178,000 sq. ft) island shaped roughly in the outline of a boat.
It's about 400 times as big as The Goodyear Blimp
In other words, 164,174,800,000 tablespoons is 423 times the size of The Goodyear Blimp, and the size of The Goodyear Blimp is 0.00236 times that amount.(for GZ-20A)
The Goodyear GZ-20 model Blimp measures 388,000,000 tablespoons in total volume. A December, 1929 college football game between the University of Florida Gators and the University of Oregon Webfoots (later the University of Oregon Ducks) began with the blimp dropping a parachute-equipped ball from a height of 61 m (200 ft) to the field below.
It's about 950 times as big as an Olympic Swimming Pool
In other words, the size of an Olympic Swimming Pool is 0.001 times 164,174,800,000 tablespoons.(FINA regulation; (minimum capacity)
According to the Fédération Internationale de Natation (FINA), a swimming pool for Olympic and world championship events must measure 50 m by 25 m with a depth of at least 2 m for a total volume of 170,000,000 tablespoons. A pool of this size was to be used in Olympic time trials in New Jersey in early 2008, but its component pieces were stolen from a warehouse, likely to be sold for scrap metal.
It's about 1,000 times as big as a Hot Air Balloon
In other words, 164,174,800,000 tablespoons is 1,100 times the size of a Hot Air Balloon, and the size of a Hot Air Balloon is 0.00091 times that amount.(four-person capacity; envelope volume; average)
The average volume of a hot air balloon sufficient to lift four adults is 150,000,000 tablespoons. Typically made of nylon or dacron, a balloon envelope of this size typically weighs just 88 kg (190 lbs).
It's about 200,000 times as big as a Concrete Mixer Truck
In other words, 164,174,800,000 tablespoons is 220,000 times the size of a Concrete Mixer Truck, and the size of a Concrete Mixer Truck is 0.00000450 times that amount.(a.k.a. cement mixer, a.k.a. cement mixer truck, a.k.a. cement transport truck, a.k.a. concrete mixer, a.k.a. concrete transport truck, a.k.a. in-transit mixer)(standard size; drum capacity)
A concrete mixer truck has a drum volume of up to 740,000 tablespoons. Concrete mixer trucks can be in transit for about 90 minutes before the concrete dries — if the concrete dries while in the drum, jackhammers or even dynamite must be used to remove it.
It's about 0.0000006 times as big as an Halley's Comet
In other words, 164,174,800,000 tablespoons is 0.000000600 times the size of an Halley's Comet, and the size of an Halley's Comet is 1,700,000 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 270,000,000,000,000,000.00000000000000000000 tablespoons. 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 0.0000006 times as big as The Grand Canyon
In other words, 164,174,800,000 tablespoons is 0.0000005820 times the size of The Grand Canyon, and the size of The Grand Canyon is 1,720,000 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 282,000,000,000,000,000.000000000000000000000 tablespoons. The strata of the rock visible in the Canyon's walls display nearly 2 billion years of geological history.
