The gram (originally gramme; [1] SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram.. Originally defined as of 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre [1 cm 3], and at the temperature of melting ice", [2] the defining temperature (≈0 °C) was later changed to 4 ...
In Canada, a teaspoon is historically 1 ⁄ 6 imperial fluid ounce (4.74 mL) and a tablespoon is 1 ⁄ 2 imperial fl oz (14.21 mL). In both Britain and Canada, cooking utensils commonly come in 5 mL for teaspoons and 15 mL for tablespoons, hence why it is labelled as that on the chart. The volume measures here are for comparison only.
For example: An acceleration of 1 g equates to a rate of change in velocity of approximately 35 km/h (22 mph) for each second that elapses. Therefore, if an automobile is capable of braking at 1 g and is traveling at 35 km/h, it can brake to a standstill in one second and the driver will experience a deceleration of 1 g. The automobile ...

Two FTUs are approximately equivalent to 1 g of topical steroid. One handprint is 0.8% (i.e. approximately 1%) of the total body surface area, [3] and one FTU covers approximately two handprints. As two FTUs are approximately equivalent to 1g of topical application, the "Rule of Hand" states that "4 hand areas = 2 FTU = 1 g". [4]
For example, SG (20 °C/4 °C) would be understood to mean that the density of the sample was determined at 20 °C and of the water at 4 °C. Taking into account different sample and reference temperatures, while SG H 2 O = 1.000 000 (20 °C/20 °C), it is also the case that SG H 2 O = 0.998 2008 ⁄ 0.999 9720 = 0.998 2288 (20 °C/4 °C).
C-6–C-7 The dram apothecaries is equal to 3 scruples (s ap or ℈) or 60 grains (gr), [5]: C-7 or exactly 3.887 9346 grams. [5]: C-14 C-14 "Dram" is also used as a measure of the powder charge in a shotgun shell, representing the equivalent of black powder in drams avoirdupois.
As a consequence, the molar mass constant remains close to but no longer exactly 1 g/mol, meaning that the mass in grams of one mole of any substance remains nearly but no longer exactly numerically equal to its average molecular mass in daltons, [30] although the relative standard uncertainty of 4.5 × 10 −10 at the time of the redefinition ...
