In practice the symbols rad and sr are used where appropriate, but the symbol for the derived unit one is generally omitted in specifying the values of dimensionless quantities."|sign=Organisation Intergouvernementale de la Convention du Mètre|source=[http://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf The International System of Units(SI)], page 26}}
