Question

how did people in earlier time measure mass​

Answer 1

Answer:

Units of mass

The grain was the earliest unit of mass and is the smallest unit in the apothecary, avoirdupois, Tower, and troy systems. The early unit was a grain of wheat or barleycorn used to weigh the precious metals silver and gold.

Answer 2

The earliest and most obvious way of measuring things was using parts of the human body. The length of a man's foreman was called a cubit. The foot was the length of an average man's foot. A fathom was the distance between the ends of a man's outstretched arms.
