**What is Weight?**

The force implied on an object due to the gravity is called as the weight of the object. The weight of the object is depended on the total mass of the object and the gravitational pull it experiences.

The weight of an same object can change based on the gravitational field, but the mass of object is always constant. For example, an object will always weigh higher than its weight on moon as the moon’s gravitational pull is lower than the earth.

**How to Use**

- The use of this weight (mass) unit converter calculator is very simple.
- To convert the unit of any weight or mass value, you need to input the weight and its unit in the respective field.
- Once you input the weight along with its unit, the tool will display its converted values in various units.

**How Many Weight (Mass) Units Can You Convert?**

We built this weight and mass converter calculator for people around the world. Our goal was to include the most important and standard weight units used globally for calculating or measuring area. Below is a list of all the weight units available for conversion.

**Metric Units:**

**Kilogram (kg)****Tonne (t)**– Also known as the Metric Ton**Gram (g)****Milligram (mg)****Microgram (µg)****Metric Ton (t)****Carat (ct)**

**Imperial/US Customary Units:**

**Imperial Ton****(long ton or ton UK)**– Also known as the British ton (2240 pounds)**US Ton****(short ton or ton US)**– Equivalent to 2000 pounds**Stone****(st)**– Equivalent to 14 pounds**Pound (lb)****Ounce****(oz)**

**How do You Convert from One Weight (mass) Unit to Another?**

Converting weight (mass) values from one unit to another is a easy process when you have the conversion factor. The conversion can be performed using either multiplication or division formulas:

**From Larger to Smaller Units:** When converting from a larger unit to a smaller unit, multiply the weight value by the conversion factor.

**From Smaller to Larger Units:** When converting from a smaller unit to a larger unit, divide the weight value by the conversion factor.

**What is a Conversion Factor?**

A conversion factor is a numerical value used to convert one unit of weight (mass) to another. It is a ratio that shows how many of one unit are equivalent to another unit. For example, 1 kilogram (kg) is equal to 2.20462 pounds (lbs). In this case, 2.20462 is the conversion factor used to convert from kilograms to pounds.

**Example : **

1. How to convert 75 kilograms into pounds?

**Solution : **

Now in the above example we have to convert the value of weight from larger unit (kilogram) to smaller unit (pounds). So in this case we will multiply the weight value.

To convert the weight (mass) value from kilogram to pound, multiply the weight value of kilograms by the conversion factor.

**Conversion Factor : 1 kilogram is equals to 2.20462 pounds.**

Pound = Weight (mass) *×* conversion factor

Pound = 75 *×* 2.20462

Pound = 165.3465

**Therefore, 75 Kg is equal to 165.3465 lb.**

**Example : **

2. How to convert 1000 gram into pounds?

**Solution : **

Now in the above example we have to convert the value of weight from smaller unit (gram) to larger unit (pounds). So in this case we will divide the weight value.

To convert the weight (mass) value from gram to pound, divide the weight value of kilograms by the conversion factor.

**Conversion Factor : 1 pound is equals to 453.592 gram.**

Pound = Weight (mass) *×* conversion factor

Pound = 1000 / 453.592

Pound = 2.20462442018

**Therefore, 1000 gram is equal to 2.2046 lb.**

**Is Weight and Mass Same?**

No, **weight** and **mass** are not the same.

**Mass**is the amount of matter in an object and is a scalar quantity. It remains constant regardless of location or gravity. Mass is measured in kilograms (kg) in the SI system.**Weight**is the force exerted on an object due to gravity. It depends on both the mass of the object and the gravitational pull at a given location. Weight is a vector quantity and is measured in**Newtons (N)**in the SI system.

The key difference is that mass is intrinsic and doesn’t change based on location, while weight can vary depending on the gravitational force. For example, your mass would be the same on Earth and the Moon, but your weight would be less on the Moon due to its weaker gravity.

**Why Do People Measure Weight in Kilograms?**

In India, and in many other countries, people often refer to “weight” in kilograms, even though technically kilograms measure mass, not weight. This practice is common due to everyday language and convenience, but it’s scientifically inaccurate.

Reason behind it:

**Historical and Practical Usage**: Over time, people became accustomed to using mass units (like kilograms) to refer to the heaviness of an object in everyday life. Most people don’t deal with situations where gravitational changes (like being on the Moon or in space) affect their understanding of weight, so they use kilograms to express what they feel as weight.**Gravitational Constant**: On Earth, the gravitational acceleration (about 9.8 m/s²) is constant in most places. Since weight is mass times gravity, people feel no practical difference between weight and mass. For example, if an object has a mass of 10 kg, its weight on Earth is roughly 98 Newtons, but because the same object would still feel “as heavy” everywhere on Earth, people just use mass as a proxy for weight.**Everyday Language vs. Scientific Precision**: In scientific terms, weight is measured in Newtons (N), but in everyday use, most people are more familiar with kilograms. So, even though they’re technically discussing mass, they use the term “weight” because it’s easier to relate to.

While it’s technically incorrect, it’s a widely accepted practice in everyday life, especially in regions like India.
