She will also do clinical work at the Chelsea Urgent Care Center, which is a unit of Mass General in Chelsea, Mass.
Gram (g), also spelled gramme, unit of mass or weight that is used especially in the centimetre-gram-second system of measurement (see International System of Units).
By international agreement the standard unit of mass, with which the masses of all other objects are compared, is a platinum-iridium cylinder of one kilogram.
The specific heat capacities (the number of heat units necessary to raise the unit of mass of a given substance one degree of temperature) of iron, aluminium and copper, for example, vary widely.
G.M. Ventures, in announcing its $7 million investment in Envia last year, noted that the company's materials would "store more energy per unit of mass than current cathode materials".
In countries that continue to favour the English system of measurement over the International System of Units (SI), the unit of mass is the slug, a mass whose weight at sea level is 32.17 pounds.
Kilogram (kg), basic unit of mass in the metric system, equal to the mass of the international prototype of the kilogram, a platinum-iridium cylinder kept at the International Bureau of Weights and Measures laboratory at Sèvres, France.
The gram, the basic unit of mass, was made equal to the mass of a cubic centimetre of pure water at the temperature of its maximum density (4 °C or 39.2 °F).
The standard for the unit of mass, the kilogram, is a cylinder of platinum-iridium alloy kept by the International Bureau of Weights and Measures, located in Sèvres, near Paris.
And it means, scientists say, that it is time to find a new way to calculate the kilogram, which currently enjoys a delightfully frustrating definition: "a unit of mass equal to the mass of the international prototype of the kilogram".
Instead of pounds, dollars or euros, we could as easily measure carbon in "Momme" (a unit of mass for measuring pearls in Japan – 1 momme = 10 fun), or "Cat" (an old American measure of the minimum fatal drug dose per kilo of cat).
