Figure 1-1 The SI length standard: the meter (a) The meter was originally defined as 1/10000000 of the distance from the North Pole to the equator along a meridian running through Paris, of which a portion was measured between Dunkirk and Barcelona. A metal bar (called the Meter of the Archives) was constructed as a standard. (b) The meter is currently defined in terms of the speed of light.

Figure 1-2a The SI mass standard: the kilogram The kilogram was originally defined in terms of a specific volume of water, that of a cube 0.10 m on a side, thereby associating the mass standard with the length standard.

Figure 1-3a The SI time standard: the second The second was once defined in terms of the average solar day. (a) It is now defined by the frequency of the radiation associated with an atomic transition.

Figure 1-5 The liter and the kilogram Other metric units are derived from the meter. (a) A unit of volume (capacity) was taken to be the volume of a cube 10 cm, or 0.01 m, on a side and was given the name liter (L). (b) The mass of a liter of water was defined to be 1 kg. Note that the decimeter cube contains 1000 cm3 or 1000 mL. Thus, 1 cm3, or 1 mL, of water has a mass of 1 g.

Figure 1-7 Comparison of some SI and British units The bars illustrate the relative magnitudes of each pair of units. (Note: The comparison scales are different in each case.)
