About Kilogram (kg)
The kilogram (kg) is the SI base unit of mass and the standard unit of weight for everyday use worldwide. Since 2019, it is defined by fixing the Planck constant (h = 6.62607015 × 10⁻³⁴ J·s), replacing the previous physical prototype kept in Sèvres, France. The kilogram is the only SI base unit still bearing a prefix ("kilo-") in its name. It is used for body weight, food packaging, luggage limits, and commerce in virtually every country that has adopted the metric system — which is all countries except the United States, Myanmar, and Liberia for everyday use.
A typical laptop weighs 1.5–2 kg. A standard bag of sugar is 1 kg. The average adult human brain weighs about 1.4 kg.
Etymology: From the French "kilogramme" (1795), combining the Greek "khilioi" (thousand) + "gramma" (small weight). The kilogram replaced older weight standards at the adoption of the metric system.
About US ton (short ton) (ton)
The US ton, also called the short ton, is a unit of mass equal to 2,000 pounds (approximately 907 kg). It is the standard large-mass unit in the United States for bulk materials such as coal, gravel, recycled metals, and agricultural commodities. The short ton is roughly 10% lighter than the metric tonne (1,000 kg) and about 12% lighter than the imperial long ton (1,016 kg). In practice, "ton" in American English almost always means the short ton. Cargo weight, construction materials, and HVAC capacity (where "ton" refers to cooling capacity derived from melting a short ton of ice per day) all use the short ton.
A pickup truck typically has a payload capacity of 0.5–1 short ton. A cord of firewood weighs roughly 2–2.5 short tons.
Kilogram – Frequently Asked Questions
How many pounds are in a kilogram?
One kilogram equals approximately 2.20462 pounds. For quick mental conversion, multiplying kg by 2.2 gives a close result. To go the other way, divide pounds by 2.2 (or multiply by 0.4536) to get kilograms.
What is the difference between kg and lbs?
Kilograms (kg) are the metric unit of mass used in most of the world; pounds (lbs) are the US customary and imperial unit. 1 kg ≈ 2.205 lbs. Body weight is expressed in kg in most countries and in lbs in the United States, which causes frequent confusion in medical, fitness, and travel contexts.
Why was the kilogram redefined in 2019?
The original kilogram was defined as the mass of a physical platinum–iridium cylinder (the International Prototype Kilogram, or IPK) stored in France. The problem was that the IPK's mass drifted over time relative to official copies. In 2019, the kilogram was redefined using the Planck constant — a fundamental constant of nature — making it stable, universally reproducible, and independent of any physical object.
What is the kilogram used for in everyday life?
The kilogram is used to express body weight, grocery and produce weight, luggage allowances on flights (typically 20–30 kg checked baggage), sports equipment weight limits, and most commercial goods. In science and engineering, it is the base unit for force (newtons), pressure (pascals), and energy (joules) calculations.
How much does a liter of water weigh in kilograms?
One liter of pure water weighs almost exactly 1 kilogram at 4°C (the temperature of maximum density). At room temperature (20°C) it is 0.998 kg — effectively 1 kg for most purposes. This relationship between liter and kilogram is not a coincidence: the liter was originally defined to make it exact.
US ton (short ton) – Frequently Asked Questions
How many pounds are in a US (short) ton?
One US short ton equals exactly 2,000 pounds (approximately 907 kg). To convert short tons to kilograms, multiply by 907.185. To convert to metric tonnes, multiply by 0.907.
What does "ton" mean in air conditioning (HVAC)?
In HVAC, a "ton of refrigeration" is a unit of cooling power equal to the heat absorbed by melting one short ton (2,000 lbs) of ice in 24 hours — approximately 3.517 kilowatts or 12,000 BTU/hour. A 3-ton AC unit has 3 × 12,000 = 36,000 BTU/h of cooling capacity. This has nothing to do with the weight of the equipment.
How many tons of food does an average person eat in a lifetime?
An average person in a developed country eats roughly 2–2.5 lbs of food per day (about 1 short ton per year). Over a 75-year lifespan, that is approximately 75 short tons (68 metric tonnes) of food — enough to fill about three standard shipping containers. Broken down: roughly 8 tonnes of fruit and vegetables, 5 tonnes of meat, 6 tonnes of grain products, 8 tonnes of dairy, and the rest in fats, sugars, and beverages. The water required to produce that food is about 50,000 tonnes — 700 times the food weight itself.
Which industries in the US still use short tons?
Short tons remain standard in US coal mining and electricity generation, steel and ferrous scrap recycling, agricultural commodities (grain, fertiliser), and construction materials (gravel, asphalt). International trade documentation typically requires conversion to metric tonnes for global contracts.
What weighs exactly one short ton that you might encounter in daily life?
A Honda Civic (2024 base model) has a curb weight of almost exactly 2,000 lbs — one short ton. A standard pallet of bottled water (84 cases of 24 × 500 mL bottles) weighs about 2,000 lbs. A cubic yard of dry sand weighs roughly one short ton. A grand piano ranges from 700 to 1,200 lbs, so you need about two of them. A typical adult horse weighs 900–1,100 lbs, so two average horses together are close to one short ton.
