Earth mass is a unit of mass equal to the mass of the planet Earth, which is about 5.9722 × 1024 kg. The web page explains how the Earth mass is measured indirectly by determining Earth's density, gravity, or gravitational constant, and what elements make up the Earth's mass. How much does Earth weigh and how is this measured? Earth weighs about 13,170,000,000,000,000,000,000,000 pounds (or 5,974,000,000,000,000,000,000,000 kilograms). Since Earth is too big to be placed on a scale, scientists use mathematics and the laws of gravity to figure out Earth's weight. · Even though we’ll never be able to pick up the Earth or place it on a giant scale, scientists have found smart ways to measure its weight. Thanks to gravity and some careful math, we know the Earth weighs nearly 6 septillion kilograms. · Learn how scientists use the Law of Universal Gravitation and Earth's radius to estimate its mass as 6 x 1024 kilograms. Find out the difference between mass and weight, and how Earth's core and mantle contribute to its mass. · How Many Tons Does the EarthWeigh? The Earth weighs approximately 5.972 × 10^24 kilograms, which is roughly 6.583 × 10^21 tons (short tons) or 5.907 × 10^21 tonnes (metric tons). · Earth weighs 5.98 × 10^24 kg (1.32 × 10^25 lbs), while the Moon weighs 7.35 × 10^22 kg (1.62 × 10^23 lbs). Earth’s surface has a gravitational acceleration of 9.8 m/s^2 (32.2 ft/s^2), compared to the Moon’s 1.625 m/s^2 (5.34 ft/s^2). 1 day ago · However, the phrasing “how muchdoes the world weigh” is technically imprecise, requiring a clarification of the distinction between mass and weight. Mass vs. Weight: Clarifying the Terminology Mass is an intrinsic property of an object that measures the amount of matter it contains and its resistance to changes in motion, known as inertia.
