BMI is a general screening measure and doesn't account for muscle mass, bone density, or body composition. It isn't a diagnosis.
Enter the loan amount, annual interest rate, and loan term in months or years, then tap Calculate EMI to see your monthly payment, total interest, and total amount payable over the life of the loan.
How is EMI calculated?
Using the standard reducing-balance formula: EMI = P × r × (1+r)^n / ((1+r)^n − 1), where P is the principal, r is the monthly interest rate, and n is the number of monthly installments.
Does this include fees or insurance?
No — this calculates principal and interest only. Add any separate fees or insurance premiums manually.
Enter the amount and tax percentage, choose whether to add or remove tax, then tap Calculate.
What's the difference between adding and removing tax?
"Add" treats your amount as the pre-tax price and calculates the tax-inclusive total. "Remove" treats your amount as already including tax and extracts the original pre-tax price.
Does this work for any country's tax rate?
Yes — enter whatever percentage applies in your region; the math is the same regardless of what the tax is called locally.
Tap the number and operator buttons to build an expression, or type directly using your keyboard. Use the DEG/RAD toggle to control how sin, cos, and tan interpret angles, then press = to evaluate.
Does this support keyboard input?
Yes — digits, + − * /, parentheses, Enter (=), Backspace, and Escape (clear) all work from your keyboard.
Degrees or radians?
Use the DEG/RAD toggle above the display — it defaults to degrees.
Pick a category, choose your From and To units, then type a value — the result updates instantly as you type.
How many categories are supported?
Eight: Length, Weight, Temperature, Area, Volume, Speed, Time, and Data Storage.
Are the conversions accurate?
Yes, using standard conversion factors; temperature uses the correct Celsius/Fahrenheit/Kelvin formulas rather than a simple multiplier.
Loading exchange rates…
Enter an amount, choose your From and To currencies, and the converted amount updates automatically using current exchange rates.
Where do the exchange rates come from?
From the free, open Frankfurter API, which publishes daily reference rates sourced from the European Central Bank.
How often do rates update?
Once per working day — this is a reliable daily reference rate, not real-time tick-by-tick trading data.
