About These Units
About Femtogram
Femtogram is an extremely small metric unit of mass equal to 10^-15 grams or one quadrillionth of a gram. This unit is part of the metric system's scientific notation approach, where the prefix 'femto-' represents a factor of 10^-15. Femtograms are primarily used in scientific research, particularly in molecular biology, nanotechnology, and atomic physics where incredibly small masses need precise measurement. This unit allows scientists to quantify the mass of individual molecules, nanoparticles, or other microscopic entities with high precision.
About Gram
The gram is a unit of mass in the metric system. The name comes from the Greek gramma, a small weight identified in later Roman and Byzantine times with the Latin scripulum or scruple (the English scruple is equal to about 1.3 grams). The gram was originally defined to be the mass of one cubic centimeter of pure water, but to provide precise standards it was necessary to construct physical objects of specified mass. One gram is now defined to be 1/1000 of the mass of the standard kilogram, a platinum-iridium bar carefully guarded by the International Bureau of Weights and Measures in Paris for more than a century. (The kilogram, rather than the gram, is considered the base unit of mass in the SI.) The gram is a small mass, equal to about 15.432 grains or 0.035 273 966 ounce. The original French spelling gramme is sometimes used. Note: The only correct symbol for the gram is g. The abbreviations "gm" and (worse) "gr" should never be used.
