Femtogram
A femtogram (fg) is a unit of mass equal to 10^-15 grams.
History/Origin
The femtogram was introduced as part of the metric system's extension to measure extremely small masses, particularly in scientific fields such as chemistry and biology, during the 20th century as measurement technology advanced.
Current Use
Femtograms are used in scientific research to measure tiny quantities of substances, such as in molecular biology, nanotechnology, and materials science, where precise measurement of very small masses is required.
Quarter (Us)
A quarter (US) is a unit of weight equal to one-fourth of a pound, commonly used in measuring precious metals and other small quantities.
History/Origin
The quarter originated from the traditional British weight system and was adopted in the United States as a subdivision of the pound. It has historically been used in commerce and trade for precise measurements.
Current Use
Today, the quarter is primarily used in the United States for measuring precious metals, jewelry, and small quantities of certain commodities. It is part of the customary units in the 'Weight and Mass' category within common converters.
