Introduction

Regarding mass, multiple unit systems are applied around the world. The International System (SI) is the most prominently recognized, employing units such as the kilogram (kg), gram (g), and decagram (dag). The Imperial System is also a notable system, which includes units like the pound (lbs) and ounce (oz).

Units of Weight

1. Kilograms (kg): The kilogram, or kilogramme, serves as the fundamental unit of mass within the International System of Units (SI), denoted by the symbol kg. Derived from the term 'one thousand grams,' it is commonly referred to as a kilo in informal settings.

2. Grams (g): The gram, an SI unit of mass with the symbol g, is equivalent to one-thousandth of a kilogram within the International System of Units (SI). Initially defined in 1795 as "the mass of a volume of pure water that is equal to the cube of the hundredth part of a meter [1 cm³] at the temperature of melting ice", the reference temperature was later adjusted to 4 °C, which corresponds to the temperature at which water reaches its maximum density.

3. Micrograms (µg): Within the metric system, the microgram, or microgramme, is a unit of mass that is equivalent to one-millionth of a gram (1×10^-6 g). The International System of Units (SI) designates the unit symbol as μg.

4. Milligrams (mg): The milligram, a metric system unit of mass, is one-thousandth of a gram. It is equivalent to the mass of one milliliter, or one-thousandth of a liter, of water at 4 degrees Celsius. The symbol for milligrams is mg.

5. Pounds (lb): The pound, also known as pound-mass, is a unit of mass used within the British imperial and United States customary systems of measurement. It is precisely established as 0.45359237 kilograms. This unit is further divided into 16 avoirdupois ounces. The recognized international standard symbol for the avoirdupois pound is "lb"; an alternative symbol employed to avoid confusion with other units, is "lbm".

6. Ounces (oz): The ounce is a unit of measurement for mass, weight, or volume that has been largely unchanged since its origin in the uncia, an ancient Roman unit of weight.

7. US Ton - Short Ton (ST): The short ton, denoted as "tn," is a unit of measurement equivalent to 2,000 pounds, or 907.18 kilograms. It is widely recognized and utilized in the United States, often being referred to colloquially as just a "ton."

8. Metric Ton (t): In the United States, the term "metric ton" is employed to differentiate it from the non-metric units such as the short ton and the long ton. The metric ton is precisely 1,000 kilograms.

Imperial Ton - Long Ton (LT):The long ton, alternatively referred to as the imperial ton or displacement ton, is a unit of measurement that equals 2,240 pounds, which is approximately 1,016.0 kilograms. This unit is what is referred to as a "ton" within the avoirdupois system of weights, or the Imperial system of measurements.

Conversion Between Different Units of Weight
