How Much Does a Quarter Weigh?

Hi there, readers!

Welcome to this comprehensive guide on the weight of a quarter. Whether you’re a curious kid, a meticulous collector, or simply want to know why quarters sink in water, we’ve got all the answers you need. Let’s dive right in and uncover the intriguing world of quarter weights!

The Basics: Mass and Weight

What is the Difference Between Mass and Weight?

Mass is the amount of matter an object contains, while weight is the force exerted on an object due to gravity. The mass of an object remains constant, but its weight can vary depending on the gravitational pull it experiences.

How Does Gravity Affect Weight?

On Earth, the acceleration due to gravity is approximately 9.8 m/s². This means that an object with a mass of 1 kilogram weighs about 9.8 Newtons. If the same object were taken to the Moon, where gravity is about one-sixth of that on Earth, it would weigh only about 1.63 Newtons.

Quarters: Composition and Weight

What are Quarters Made Of?

U.S. quarters are composed of a copper-nickel alloy known as cupronickel. This alloy is 75% copper and 25% nickel. Quarters minted before 1965 were made of 90% silver and 10% copper.

How Much Does a Quarter Weigh?

The weight of a quarter depends on its year of mintage. Quarters minted after 1965 weigh approximately 5.67 grams or 0.2 ounces. Quarters minted before 1965 weigh slightly more, at about 6.25 grams or 0.22 ounces.

Interesting Facts About Quarter Weights

Why Do Quarters Sink in Water?

Despite their metallic composition, quarters sink in water because their density is greater than that of water. Density is the mass of an object per unit volume. Quarters have a density of about 8.9 grams per cubic centimeter, while water has a density of about 1 gram per cubic centimeter.

The Quarter as a Unit of Measurement

In some informal settings, quarters are occasionally used as a unit of measurement for very small amounts of drugs. This is known as a "quarter hit," which is equivalent to about 0.25 grams of a substance.

Fractional Weights of Quarters

Quarters can be divided into fractional weights. A half quarter weighs approximately 2.83 grams, while a quarter of a quarter weighs approximately 1.42 grams.

Table: Quarter Weights Over Time

Year Range Quarter Type Weight in Grams Weight in Ounces
Pre-1965 Silver 6.25 0.22
1965-Present Cupronickel 5.67 0.2
Half Quarter Cupronickel 2.83 0.1
Quarter of a Quarter Cupronickel 1.42 0.05
