• Symbol: The symbol for nanogram is “ng.”

• Usage: Nanograms are frequently used in fields like chemistry, biology, and medicine to quantify substances that exist in minute amounts.

Origin of the stone

• The term “stone” as a unit of measurement has its origins in the practice of using actual stones for weighing goods in ancient times, particularly in the British Isles. The use of stones as a unit became standardized in the 14th century, with 14 pounds being established as the weight of one stone.

Origin of the nanogram
