BMI Calculator
Check your Body Mass Index from height and weight.
How it works
BMI is calculated as weight in kilograms divided by height in metres squared. A value under 18.5 is considered underweight, 18.5–24.9 is normal, 25–29.9 is overweight, and 30 or above is obese. BMI is a general screening guide, not a medical diagnosis. Read more in our guides.
Loan / EMI Calculator
Find your monthly payment for any loan.
How it works
This tool uses the standard amortization formula to spread your loan amount plus interest evenly across each month of the term. The total interest figure shows how much the loan costs you on top of the amount you borrowed.
Age Calculator
Find your exact age in years, months, and days.
How it works
The age calculator counts the precise time between your birth date and today, automatically accounting for leap years and the different number of days in each month.
Percentage Calculator
Work out what X% of a number is, quickly.
How it works
The calculator multiplies the value by the percentage divided by 100. It is handy for working out tips, discounts, taxes, and exam grades in seconds.
Unit Converter
Convert between common length and weight units.
How it works
The converter works within the same category — length (km, mi, m, ft, cm, in) or weight (kg, lb). Trying to convert a length into a weight will show an error.
