About MEP Analysis
MEP Analysis is a free collection of engineering calculators for Mechanical, Electrical and Plumbing (MEP) work in India. It helps engineers, contractors, site supervisors and students do quick preliminary calculations, with the formula and a worked example shown on every page, so the result can be checked by hand.
Who runs this site
MEP Analysis is created and maintained by K. K. Kranti (Karmath Kumar Kranti), who holds a B.Tech in Electrical Engineering and has more than 15 years of experience in building services, HVAC, electrical design and site execution. The calculators come from the kind of checks that are done again and again on real projects, such as sizing a cable, estimating an AC or working out a pump or a fire water tank.

What you will find here
Calculators are grouped by trade, so you can go straight to the one you need:
- Electrical
- HVAC
- Fire and Safety
- Plumbing
- General
- Civil
The full and current list is always on the Calculators page. Every calculator page has the formula, at least one worked example, a list of common mistakes and a short FAQ. You can also download your result as a PDF for your calculation file.
How the calculators are built
- The formula is always visible. Nothing is hidden, so you can repeat the calculation by hand.
- Worked examples are checked by hand before they are published.
- Inputs start empty on purpose, so a value from an earlier job never slips into a new calculation.
- Calculations run in your browser. The numbers you enter are not stored by us.
Standards and sources
Where a standard or method applies, it is named on the calculator page. These include IEC, IS codes, NEC, the National Building Code of India (NBC) and ASHRAE/ISHRAE guidelines. Some values, such as typical heat gain figures, are planning values and are labelled that way on the page.
What these tools are, and what they are not
The results are for preliminary estimation, quick checks, learning and early design stages. They do not replace a code review, a site survey, a full heat load calculation or the judgement of a qualified engineer. Please verify any final design against the code that applies to your project. Read the Disclaimer for details.
Corrections and suggestions
If you think a result or explanation is wrong, or you want a calculator that is not here yet, please use the Contact page or email contact@mepanalysis.in. Tell me the calculator name, your inputs and what you expected. Every report is reviewed.
