Abstract.
The star formation rate (SFR) in galaxies is of prime importance in
the study of formation and evolution of galaxies. Different methods
have hence been evolved to estimate the current SFR in galaxies,
using indicators at different wavelengths. These methods are
reviewed briefly. While there is a good correlation between
different estimators, one needs to exercise caution while applying
any single method to an individual galaxy,or more particularly, an
individual star forming region. However, the availability of data at
several wavelengths helps in understanding the environments of
different types of galaxies, and an individual starforming region
better.
Key words: stars: formation -- galaxies: stellar content
