Unit Explanations
Kilogramkg
Source UnitThe kilogram, abbreviated as kg, is the SI unit of mass and is defined as being equal to the mass of the International Prototype of the Kilogram, which is a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in Sèvres, France. This definition was established in 1889 and was the only base unit defined by a physical object. However, in 2019, the definition of the kilogram was redefined in terms of fundamental constants, specifically the Planck constant (h), which is set at exactly 6.62607015 × 10^-34 joule seconds. This redefinition allows for more precise measurements and ensures that the kilogram remains consistent and reproducible over time.
Current Use
Today, the kilogram is widely used across the globe as the standard unit of mass in scientific, commercial, and everyday contexts. It is employed in various industries including manufacturing, agriculture, and healthcare. For instance, in the food industry, products are often sold by mass, measured in kilograms. In healthcare, medication dosages may also be prescribed based on the patient’s weight in kilograms. While most countries use the kilogram as part of the metric system, some countries, such as the United States, still use imperial units for certain applications, though the metric system is increasingly adopted in scientific and technical fields. The versatility of the kilogram makes it a vital unit in international trade and commerce.
Fun Fact
The kilogram was the first unit of measurement to be defined by a physical artifact.
Ton of RefrigerationTR
Target UnitThe ton of refrigeration (TR) is a unit of power used to describe the cooling capacity of a refrigeration system. It is defined as the amount of heat required to melt one short ton (2,000 pounds) of ice in a 24-hour period. One ton of refrigeration is equivalent to 12,000 BTU per hour or approximately 3.517 kilowatts. This unit is commonly utilized in the United States and Canada to quantify the cooling capacity of air conditioning units and refrigeration systems, providing a practical measure for engineers and consumers.
Current Use
Today, the ton of refrigeration is widely used in HVAC (heating, ventilation, and air conditioning) industries to describe the cooling capacity of systems. It provides a convenient unit for engineers and consumers to understand and compare the cooling capabilities of different systems. The unit is particularly important in North America, where it is a standard measure for air conditioning systems in residential, commercial, and industrial applications.
Fun Fact
A ton of refrigeration is equivalent to melting about 1 ton of ice in 24 hours.
Convert Kilogram to Ton (kg to t)
Precise conversion from Kilograms (kg) to Metric Tons (t). This conversion is crucial for shipping, logistics, industrial manufacturing, and large-scale commerce where weights are measured in thousands of kilograms.
To convert kilograms to metric tons, divide the weight value by 1000. For example, 5000 kg ÷ 1000 = 5 metric tons. One metric ton equals exactly 1000 kilograms.
Kilogram (kg)
Definition
The kilogram is the base unit of mass in the International System of Units (SI). It is defined by the Planck constant, exactly 6.62607015×10⁻³⁴ joule-seconds.
Origins & History
Originally defined in 1795 as the mass of one liter of water at 4°C. From 1889 to 2019, it was defined by the International Prototype Kilogram (IPK), a platinum-iridium cylinder. The current definition based on fundamental constants was adopted in 2019.
Metric Ton (t)
Definition
The metric ton, also called tonne, is a unit of mass equal to 1000 kilograms or approximately 2204.62 pounds. It is not an SI unit but is accepted for use with SI.
Origins & History
The metric ton was introduced along with the metric system in the late 18th century. It provides a convenient unit for measuring large masses in commerce and industry.

Definition
The kilogram, abbreviated as kg, is the SI unit of mass and is defined as being equal to the mass of the International Prototype of the Kilogram, which is a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in Sèvres, France.

This redefinition allows for more precise measurements and ensures that the kilogram remains consistent and reproducible over time.
History & Origin
The kilogram originated in the late 18th century during the period of the French Revolution, as part of the efforts to standardize measurements across France and eventually the world. The need for a uniform measurement system became apparent in the wake of the Revolution, as varying local measures were causing confusion and inefficiency in trade and governance. Thus, the metric system was born, with the kilogram being one of its foundational units. The first kilogram was defined as the mass of one liter of water at its maximum density, which is approximately equal to 1,000 cubic centimeters. This practical approach to defining mass allowed for easier adoption across various sectors.
Etymology: The term 'kilogram' is derived from the Greek word 'kilo', meaning 'a thousand', and the French word 'gramme', which itself comes from the Late Latin 'gramma', meaning 'small weight'.

💡 Fun Facts
- •The kilogram was the first unit of measurement to be defined by a physical artifact.
- •The International Prototype of the Kilogram lost mass over time, leading to the redefinition in 2019.
- •The kilogram is the only SI base unit with a prefix ('kilo') included in its name.

History & Origin
The concept of ton of refrigeration originated in the late 19th century when large blocks of ice were used to cool industrial and commercial spaces. The unit was developed to quantify the cooling effect of melting ice, which was a common method of refrigeration before mechanical systems became widespread. This historical context underscores the practicality of the unit in early industrial applications.
Etymology: The word 'ton' comes from the Latin 'tunella', a large cask used in trade, and 'refrigeration' is derived from the Latin 'refrigerare', meaning to cool.
