It's about fifteen times as heavy as a Mouse
In other words, the weight of a Mouse is 0.067 times 0.000000000310 megatonnes.(a.k.a. "House mouse", Mus musculus) (adult)
The weight of a mouse is typically an average of 0.0000000000210 megatonnes. While most mice typically live two to three years, the Methuselah Mouse Prize — an award administered by a non-profit organization which advances aging-related research — was once awarded to a team of scientists whose research resulted in a mouse living just under five years.
It's about one-fifteenth as heavy as a Gallon of Paint
It's about twenty times as heavy as a Compact disc
It's about one-twentieth as heavy as a Bowling Ball
In other words, 0.000000000310 megatonnes is 0.0455622009 times the weight of a Bowling Ball, and the weight of a Bowling Ball is 21.94801790 times that amount.(most common selection among male bowlers)
With an allowable range of 0.000000004989516070 megatonnes, the most-preferred bowling ball weight among adult, male bowlers is 0.000000006803885550 megatonnes. Because regulation balls measure the same diameter irrespective of their weight, ball density varies by size and balls weighing less than about 0.00000000500 megatonnes will float in water.
It's about thirty times as heavy as a Battery (AAA)
In other words, the weight of a Battery (AAA) is 0.038 times 0.000000000310 megatonnes.(Alkaline)
An "AAA" size battery weighs 0.0000000000120 megatonnes. Batteries are named by the American National Standards Institute (ANSI) Committee C18 and AAA batteries were given their name because they were smaller than the "AA" and "A" size batteries which were invented first.
It's about one-thirty-fifth as heavy as a Dachshund
In other words, the weight of a Dachshund is 30 times 0.000000000310 megatonnes.(a.k.a. "Wiener dog", a.k.a. Teckel, a.k.a. Dackel, a.k.a. "hot dog dog", a.k.a. "sausage dog", a.k.a. "doxie") (FCI standard; standard size)
The Fédération Cynologique Internationale (FCI) calls for dachshunds to weigh about 0.00000000900 megatonnes. Despite of their small size, a 2008 survey conducted by the University of Pennsylvania named dachshunds as the most aggressive dog breed.
It's about one-fortieth as heavy as a Gold Bar
In other words, 0.000000000310 megatonnes is 0.02491682859 times the weight of a Gold Bar, and the weight of a Gold Bar is 40.133518450 times that amount.(London Good Delivery bar)
A "London Good Delivery" gold bar — the variety commonly held by Central Banks — should weigh 0.000000012441390720 megatonnes. The largest gold bar ever produced was minted by Mitsubishi Materials Corporation (a sibling company of the auto manufacturer) in 2005 and weighed 0.000000250 megatonnes.
