What does 1 quarter (US) represent in mass?

One US quarter (qr US) is defined as one quarter of a US hundredweight, equivalent to 25 pounds or approximately 11.3398 kilograms.

What is an attogram used for?

An attogram is an SI unit of mass measuring 10^-18 grams, used to quantify tiny masses such as single molecules or nanoparticles in scientific fields.

Why convert from quarter (US) to attogram?

This conversion allows bridging traditional US customary mass units with extremely small SI units, useful in fields like analytical chemistry, nanotechnology, and environmental science.
