About ToolKit Pro
Free, fast, privacy-first online tools — built by a team of engineers, a practising physician and a chartered accountant. Every calculation, formula and recommendation on this site is reviewed against primary sources before it goes live.
Our mission
Make essential digital utilities — calculators, converters, generators and developer tools — accessible to everyone in the world, free of cost, with privacy as the default. No signup, no tracking beyond standard analytics, no walls around the answer you came for.
How we maintain accuracy
- Primary sources only. Unit conversion factors are taken from the BIPM SI Brochure (9th edition) and NIST Special Publication 811. Health ranges follow current WHO guidance. Loan formulas match the published amortisation methodology used by major retail lenders.
- Two-stage review. Every new page is written by a named author with relevant credentials and reviewed by a second team member before publication.
- Re-verified twice a year. All conversion factors, formulas and health/finance recommendations are re-checked every six months and stamped with a visible "last reviewed" date.
- Corrections welcome. If you spot an error, write to us via /contact — verified corrections ship within 48 hours.
The team
ToolKit Pro is intentionally a small editorial team — fewer voices, higher accountability for what we publish.
Our editorial team verifies every formula, unit factor and recommendation against primary sources (NIST, BIPM, WHO, RBI) before publication. Every page is reviewed at least twice a year for accuracy and freshness.
Amit founded ToolKit Pro to give students and professionals a single fast, ad-light home for the calculators and converters they use daily. He writes the developer-focused guides (JSON, Base64, UUID, URL encoding).
Dr. Menon reviews every health-related calculator and guide on ToolKit Pro (BMI, healthy-weight, body composition). Her clinical practice spans primary care, weight management and adolescent health.
Rahul writes the EMI, loan and personal-finance content. He has structured home, personal and auto loan products at two major Indian banks and verifies every formula against published lender disclosures.
Sara owns the unit-conversion pages. She cross-checks every factor against the BIPM SI brochure (9th edition) and NIST Special Publication 811 so the numbers you see match the ones used in science and trade.
