Star formation rates for a cloud with a mean density of 100 cm-3 and varying mass, calculated with different star formation criteria: the CMF formalism, the Krumholz & McKee (2005) formalism, and two constant-threshold criteria. In the high-threshold case (105 cm-3), virtually no stars are formed even for massive clouds while all other criteria yield comparable SFRs and show similar scaling.
