What is yottagram?

Yottagram is a unit of measurement used to describe mass. It is equivalent to one quadrillion (1,000,000,000,000,000) grams. The prefix "yotta" represents a factor of 10^24, which is the largest factor used in the International System of Units (SI). Yottagrams are typically used in astronomy to measure the mass of celestial bodies such as stars and galaxies. It is also used in the field of nuclear physics to describe the mass of atomic nuclei. Despite its immense size, yottograms are not used frequently in everyday life as most objects have a much smaller mass.
