They are in roman type if they are descriptive. The following forms, for example, are used instead. Commas are not used to separate digits into groups of three. When a numerical-value equation is used, it is properly written and the corresponding quantity equation is given where possible. Similarly, standardized mathematical signs and symbols are used. More specifically, the base of "log" in equations is specified when required by writing log a x meaning log to the base a of x , lb x meaning log 2 x , ln x meaning log e x , or lg x meaning log 10 x.
In science and technology, weight is a force, for which the SI unit is the newton; in commerce and everyday use, weight is usually a synonym for mass, for which the SI unit is the kilogram. Note the difference between "surface" and "area," "body" and "mass," "resistor" and "resistance," "coil" and "inductance.
Return to Units home page. Only units of the SI and those units recognized for use with the SI are used to express the values of quantities. Abbreviations such as sec, cc, or mps are avoided and only standard unit symbols, prefix symbols, unit names, and prefix names are used. Unit symbols are unaltered in the plural. Unit symbols are not followed by a period unless at the end of a sentence. The length of the bar is 75 cm. Get Full Solutions.
