What is a Kilogram and a Ton (US)?

The kilogram is the base unit of mass in the International System of Units (SI). It is defined based on the fixed numerical value of the Planck constant.

The US ton, also known as the short ton, is a unit of mass commonly used in the United States. It is defined as exactly 2,000 pounds (avoirdupois). This is equivalent to 907.18474 kilograms.

Note: The Kilogram is part of the metric (SI) system, primarily used globally in science and trade. The Ton (US) belongs to the imperial/US customary system.

History of the Kilogram and Ton (US)

Originally defined as the mass of one liter of water. Later, it was represented by the International Prototype of the Kilogram (IPK), a platinum-iridium cylinder. In 2019, the definition was changed to be based on fundamental physical constants.

The short ton originated in the English system of weights and measures and became the standard ton in the United States. It differs from the imperial (long) ton (2,240 lbs) used more traditionally in the UK, and the metric ton (1,000 kg).

Common Uses for kilograms and US tons

Explore the typical applications for both Kilogram (metric) and Ton (US) (imperial/US) to understand their common contexts.

Common Uses for kilograms

Global Standard: The primary unit for mass in science (physics, chemistry), engineering calculations, and international trade (e.g., commodity pricing).
Body Weight: Widely used worldwide (outside the US/UK primarily) for measuring human body weight for health and fitness tracking.
Food & Groceries: Used for selling and labeling larger quantities of food items like rice, flour, sugar, and some produce in metric countries.
Shipping & Logistics: Standard unit for calculating weights of packages and freight internationally.
Everyday Objects: Measuring the mass of common items like furniture, electronics, or luggage.

Common Uses for US tons

Transportation: Measuring vehicle weights and payload capacities in the US for trucks, trailers, and commercial vehicles.
Construction Materials: Used for quantifying bulk materials like gravel, sand, and coal in US commerce and construction projects.
Industrial Applications: Standard unit for heavy machinery, shipping containers, and large-scale manufacturing within the US.
HVAC Systems: Often used for measuring large items like HVAC units (tonnage rating relates to cooling capacity, but derives from the weight of ice).
Waste Management: Common unit for measuring municipal solid waste, recycling volumes, and landfill capacities.

Frequently Asked Questions

Questions About Kilogram (kg)

What is the base unit of mass in the SI system?

The kilogram (kg) is the base unit of mass in the International System of Units (SI).

Is the kilogram used worldwide?

Yes, it's the global standard for science, engineering, and international trade, and widely used for everyday measurements in most countries.

How was the kilogram originally defined?

It was initially defined as the mass of one liter of water, later represented by a physical artifact (the IPK), and is now based on the Planck constant.

About Ton (US) (ton)

How many pounds are in a US ton?

There are exactly 2,000 pounds (lb) in 1 US ton (short ton).
