What is a microgram?
A microgram is a unit of mass in the metric system that is equal to one millionth of a gram. It is commonly used to measure very small amounts of substances, such as medications, vitamins, or pollutants. The symbol for microgram is μg. To put it into perspective, a single grain of table salt typically weighs around 58,500 micrograms.
What is a long ton (imperial ton)?
A long ton, also known as an imperial ton, is a unit of weight commonly used in the United Kingdom and some other Commonwealth countries.
It is equivalent to 2,240 pounds or 1,016 kilograms. The long ton is primarily used in the context of trading goods, particularly in industries such as shipping, agriculture, and mining.
In terms of metric conversions, a long ton is equal to approximately 1.016 metric tonnes. This means that one long ton is slightly heavier than one metric ton, which is equivalent to 1,000 kilograms. The long ton is not commonly used in countries that have adopted the metric system, but it is still relevant in certain industries and historical contexts where imperial units are preferred.
