▪ He is popularly known for the development in 1920 of the Saha equation or Ionisation Equation.

▪ For his great contribution on the Saha's equation he got nominated in 1930 for the Nobel Prize in Physics but he missed as because the Nobel Committe said it as a useful application but not a "discovery". And after this he was nominated many times in physics.

▪ He also invented an instrument to calculate the weight and pressure of solar rays.

▪ He was the chief architect of river planning and development in India. He made the original plan for the Damodar Valley Project in West Bengal.
