It's about 450,000,000 times as heavy as a Tennis Ball.

Per International Tennis Federation standard, regulation tennis balls must weigh about 0.00005770 tonnes. Competition balls are also tested for bounce height, with the standards requiring that a ball dropped from 254 cm must bounce back to a height of 135 cm to 147 cm.
It's about 550,000,000 times as heavy as a Golf Ball.
In other words, 25,000 tonnes is 544,300,000 times the weight of a Golf Ball, and the weight of a Golf Ball is 0.0000000018370 times that amount.(per R&A USGA Rules of Golf; maximum rule weight)
According to the Rules of Golf (as approved by the United States Golf Association and the Rules Committee of the Royal and Ancient Golf Club of Saint Andrews), golf balls must weigh no more than 0.000045930 tonnes. Golf balls are not required to have the familiar dimpled pattern, but the design has been popular since its invention in 1905 because it reduces drag while increasing lift.
It's about 750,000,000 times as heavy as a Light Bulb.
In other words, the weight of a Light Bulb is 0.00000000140 times 25,000 tonnes.(a.k.a. lamp) (for A19-size, 60w, incandescent bulb by Bulbrite; package weight)
A standard, sixty-watt light bulb weighs about 0.0000340 tonnes. The tightly-coiled filament inside a bulb of this size would measure about 579mm if uncoiled and stretched out.
It's about 1,000,000,000 times as heavy as a Battery (AA).
In other words, the weight of a Battery (AA) is 0.000000001000 times 25,000 tonnes.(Alkaline)
An "AA" size battery weighs 0.0000240 tonnes. AA batteries came into common use during World War II and were given their name by the American National Standards Institute (ANSI) Committee C18 because they were smaller than the "A" size batteries which were invented first.
It's about 1,000,000,000 times as heavy as a Mouse.
In other words, 25,000 tonnes is 1,200,000,000 times the weight of a Mouse, and the weight of a Mouse is 0.000000000830 times that amount.(a.k.a. "House mouse", Mus musculus) (adult)
The weight of a mouse is typically an average of 0.0000210 tonnes. 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 1,500,000,000 times as heavy as a Compact disc.
It's about 2,000,000,000 times as heavy as a Battery (AAA).
In other words, 25,000 tonnes is 2,100,000,000 times the weight of a Battery (AAA), and the weight of a Battery (AAA) is 0.000000000480 times that amount.(Alkaline)
An "AAA" size battery weighs 0.0000120 tonnes. 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.
