Weighs Or Weights

When it comes to measuring the mass or heaviness of an object, two terms tend to be frequently used – weight and weigh. While both words are often used synonymously, they have two distinct meanings.

Weigh is a verb that refers to the process of measuring the mass or heaviness of an object using a scale or a balance. In a broader sense, it can also mean estimating the value or significance of something. For instance, “I need to weigh myself on the scale,” or “I need to weigh the pros and cons of this decision.”

On the other hand, weight is a noun that refers to the actual heaviness or mass of an object. It is the force exerted by gravity on any body having mass. For example, if an object weighs 10 kilograms on earth, it will weigh significantly less on the moon due to the moon’s weaker gravitational force.

In essence, weigh is a process of determining weight, whereas weight is the actual value or measurement of heaviness. Both terms are useful in understanding the nature of mass and its relationship to gravity.


Weight can be defined as the mass of an object multiplied by the acceleration due to gravity. The formula for calculating weight is W= mg, where W is weight, m is mass, and g is the acceleration due to gravity. The average acceleration due to gravity at the Earth’s surface is 9.81 meters per second squared (m/s²). This means that a 1-kg object weighs approximately 9.81 Newtons on the surface of the Earth.

Weight is often measured in units such as Newtons or pounds. In the United States, commonly-used units of force are pounds (lb) and ounces (oz), while in most other countries, the metric system is used, and force is measured in Newtons.


Weights are objects used to add additional mass or pressure to an object to make it heavier or difficult to lift. They can come in various shapes, sizes, and materials, such as steel, concrete, or plastic. Weights are commonly used in exercise machines and equipment and provide resistance to the body, improving strength and endurance.

Depending on the type of exercise, different weights can be used for different muscle groups to achieve specific training goals. For example, lighter weights with more repetitions can help build endurance, while a heavier weight with fewer repetitions can help build strength.


As mentioned earlier, weight and weigh are often confused, and people often use them interchangeably. While they may seem interchangeable, it’s essential to understand their differences as they have different applications.

Weight is a physical characteristic of an object that determines its heaviness. It is measured using units of mass, which can be converted into a force measured in Newtons, and can be affected by numerous factors, such as altitude or gravity.

Weigh, on the other hand, is the process of determining how heavy something is using a device, such as a scale or balance. Although it’s often used in determining the weight of objects, it can also refer to estimating the value or significance of something.


1) What is the difference between mass and weight?

Mass is a measure of the amount of matter in an object, while weight is the measure of the gravitational force exerted on an object. Therefore, the mass of an object remains the same regardless of its location, while weight can vary depending on the strength of gravity.

2) How does gravity affect weight?

Gravity is the force that attracts objects toward each other, and it affects the weight of an object by acting on its mass.

3) What is the significance of weights in exercise?

Weights provide resistance to the body, strengthening and conditioning the muscles. Different weights can be utilized for specific muscle groups to achieve specific training goals, such as building muscle endurance and strength.


In conclusion, weigh and weight are both words used regularly when discussing the mass of an object. Although they are related concepts, they have different meanings and applications. Weight refers to the actual mass of an object, whereas weigh refers to the process of measuring its mass. It’s essential to understand the differences between the two terms to use them correctly in communication.
