Using the Calculators

General guidelines applicable to all calculators.

How to Use:
  1. Select the appropriate calculator for your design task
  2. Enter the required input parameters
  3. Click "Calculate" to process the inputs
  4. Review the results and design checks
  5. Adjust parameters as needed and recalculate
Important Notes:
  • All calculations are based on Indian Standard codes
  • Results should be verified by a qualified engineer
  • Input values outside recommended ranges may produce unreliable results
  • The calculators provide educational guidance and should not replace professional judgment
