We want to help people make better decisions that rely on numbers, not intuition. If you are a scientist, educator, NGO worker, advocate of a social cause, or a professional who wants to use our calculators to reach a wider audience, we would love to collaborate with you.
We create calculators that use scientific and statistical formulas to help explain complex phenomena in plain terms. We can build a calculator that supports your research, put together a collection of tools for a topic you are teaching, quantify the problem you are trying to solve, and engage others in your cause.
In a nutshell — if you too think in algorithms, we can help turn them into interactive tools that highlight your expertise and share it with the world.
Did you know you can embed Joteo calculators on your own website? Every calculator on Joteo can be embedded as a widget — perfect for university departments, research blogs, and educational platforms that want to keep visitors engaged without building tools from scratch. Get in touch to learn how.

We partnered with Prof. Satyajit Mayor, Senior Professor at the National Centre for Biological Sciences (NCBS-TIFR), Bangalore, on our Biology tools. A recipient of the Shanti Swarup Bhatnagar Prize and the Infosys Prize for Life Sciences, his laboratory studies cell membrane organisation, endocytosis, and protein trafficking — the cellular processes that underpin our pharmacokinetics, drug half-life, and cell division calculators.
Prof. C. N. R. Rao, Linus Pauling Research Professor at JNCASR, Bangalore, and recipient of the Bharat Ratna, is India's most decorated living chemist. With over 1,500 research papers, 45 books, and more than 125,000 citations, his foundational contributions to solid-state chemistry, stoichiometry, and chemical bonding make him the definitive authority behind our Chemistry tools — from molar mass and pH calculators to reaction yield and concentration converters.
We work with Prof. Vasant Matsagar, Dogra Chair Professor and Head of Civil and Environmental Engineering at IIT Delhi, on our Construction category. A Humboldt Research Fellow and Carl Friedrich von Siemens Award winner with over 8,500 citations, his Multi-Hazard Protective Structures Laboratory specialises in structural load analysis, concrete design, and earthquake engineering — exactly the science behind our concrete mix, load-bearing, and material volume calculators.
Prof. T. V. Ramachandra of the Centre for Ecological Sciences at the Indian Institute of Science (IISc), Bangalore, collaborates with us on Ecology tools. With over 22,000 citations and five consecutive appearances on Stanford's World's Top 2% Scientists list, his work on carbon footprints, biodiversity metrics, ecosystem services, and water usage modelling in Indian landscapes directly shapes how our ecology and sustainability calculators present environmental impact to a general audience.
We teamed up with Prof. U. Dinesh Kumar, Professor of Quantitative Methods and Decision Sciences at IIM Bangalore — the academic who introduced Business Analytics education to India — to review our Education & Academic tools. Author of the widely used textbook Business Analytics: The Science of Data-Driven Decision Making, his expertise in learning metrics, performance measurement, and statistical modelling ensures our GPA, grade, and academic performance calculators meet the highest standard.
Prof. Mahesh B. Patil, Professor in the Department of Electrical Engineering at IIT Bombay, has taught circuit theory, Ohm's law, and power electronics for over two decades and won the institute's Excellence in Teaching award. He is the creator of SEQUEL, an open-source circuit simulator widely used across Indian universities for analysing resistor, capacitor, and inductor networks. His work directly powers the computational accuracy of our Electrical & Electronics calculator suite.
With Prof. Manjul Bhargava, Fields Medal laureate (2014) and R. Brandon Fradd Professor of Mathematics at Princeton University — who holds adjunct professorships at IIT Bombay, TIFR, and the University of Hyderabad — we bring the world's highest mathematical authority to our Everyday Life tools. Few scientists communicate the practical power of numbers as vividly as Manjul. His connection to India's premier research institutions means our everyday arithmetic, unit conversion, and percentage tools benefit from a uniquely Indian-rooted mathematical rigour.
Prof. Jayanth R. Varma, Distinguished Professor of Finance at IIM Ahmedabad, former full-time member of SEBI, and current external member of the RBI Monetary Policy Committee, advises on our Finance category. His career-long research on compound interest, loan pricing, mortgage valuation, derivatives, and risk management means every formula in our finance calculator suite — from EMI to retirement planning — has been stress-tested by one of India's foremost financial economists.
We partnered with Prof. Anura V. Kurpad, Professor of Physiology at St John's Medical College, Bangalore, and chair of the ICMR Expert Committee on Nutrient Requirements of Indians, on our Food tools. A Fellow of the Royal College of Physicians (London) and named 2026 Distinguished Fellow of the American Society for Nutrition, his 600+ publications on caloric requirements, macronutrient metabolism, and protein intake across the Indian life cycle are the scientific foundation for our calorie count, recipe scaling, and macronutrient calculators.
Prof. Rajesh Khadgawat, Professor of Endocrinology at AIIMS New Delhi, collaborates with us on Health & Fitness tools. With 233+ publications on BMI assessment, body composition, metabolic disorders, and hormonal regulators of fitness in Indian populations, his clinical and research expertise directly validates our BMI, TDEE, body fat percentage, and heart rate zone calculators for South Asian users who are frequently underserved by tools calibrated only for Western populations.
We work with Prof. Arup Bose, HAG Professor at the Statistics and Mathematics Unit of the Indian Statistical Institute (ISI), Kolkata, on our Mathematics tools. A Fellow of the Indian Academy of Sciences, the Indian National Science Academy, and winner of the Shanti Swarup Bhatnagar Prize, his 150+ papers on random matrices, algebra, and probability provide the rigorous mathematical grounding behind our arithmetic, geometry, trigonometry, and percentage calculators.
Prof. Deepak Dhar, INSA Distinguished Professor at IISER Pune and Emeritus Distinguished Professor of TIFR, became the first Indian physicist to receive the Boltzmann Medal (2022) — the highest honour in statistical physics — and was awarded the Padma Bhushan in 2023. With over 9,200 citations for his foundational work on thermodynamics, phase transitions, and statistical mechanics, he reviews our Physics calculator suite covering kinematics, thermodynamics, fluid dynamics, and optics.
Together with Prof. M. S. Santhanam, Professor of Physics at IISER Pune, we bring data-driven rigour to our Sports category. His research group produced the first comprehensive statistical analysis of individual and team performance in One-Day International cricket — one of the most cited quantitative studies of cricket globally. His broader expertise in complex networks and statistical data science underpins our pace calculators, batting average models, sprint analysis tools, and cricket-specific performance metrics.
Prof. Rahul Siddharthan, Professor at the Institute of Mathematical Sciences (IMSc), Chennai, advises on our Statistics tools. After postdoctoral fellowships at Rockefeller University and École Normale Supérieure, he returned to India where he has published widely on Bayesian methods, statistical inference, regression models, and hypothesis testing. His expertise directly validates our mean, standard deviation, p-value, and confidence interval calculators.
Finally, Prof. Prabha Mandayam, Associate Professor of Physics at IIT Madras, contributes to our Time & Date tools. Her research in quantum information theory, quantum error correction, and synchronisation — disciplines demanding extreme precision in time measurement — brings a uniquely rigorous perspective to our time-zone, countdown, working-days, and date-difference calculators. She earned her PhD at Caltech under Prof. John Preskill and leads IIT Madras's quantum computing initiatives as a member of India's National Quantum Mission research committee.
