Convert between different distance and length units including meters, kilometers, miles, feet, yards, inches, centimeters, and millimeters.

Convert between different speed units including meters per second, kilometers per hour, miles per hour, knots, and feet per second.

Convert between different time units including seconds, minutes, hours, days, weeks, months, years, and milliseconds.

Convert between different weight and mass units including kilograms, grams, pounds, ounces, metric tons, stone, and milligrams.

Convert between different volume units including liters, milliliters, US gallons, quarts, pints, cups, fluid ounces, cubic meters, cubic feet, and cubic inches.

Convert between different temperature scales including Celsius, Fahrenheit, and Kelvin.

Calculate your Body Mass Index (BMI) using height and weight. BMI is a measure of body fat based on height and weight. The calculator will show your BMI value and category (Underweight, Normal weight, Overweight, or Obese). Note: BMI is a screening tool and may not accurately reflect body fatness in all individuals, particularly athletes or older adults.

Estimate your body fat percentage using the U.S. Navy method based on height, weight, waist circumference, age, and gender. This provides an approximation of body composition. Note: This is an estimation method and may not be accurate for all body types. For precise body composition analysis, consult a healthcare provider.

Calculate your ideal weight range based on your height and gender using the Robinson formula. This determines a healthy weight range for maintaining optimal health. Note: Ideal weight is a general guideline and may vary based on body composition, muscle mass, age, and other factors.

Calculate your Basal Metabolic Rate (BMR) - the number of calories your body burns at rest. This uses the Mifflin-St Jeor Equation, which is considered one of the most accurate formulas. BMR is essential for understanding your daily calorie needs. Note: BMR values are estimates and actual metabolic rate can vary based on many factors including genetics, medications, and medical conditions.

Calculate your Total Daily Energy Expenditure (TDEE) - the total number of calories you burn per day including all activities. TDEE is calculated by multiplying your BMR by an activity factor based on your exercise level. This is useful for weight management goals. Note: TDEE values are estimates and actual energy expenditure varies day-to-day. Activity factors are approximations.

Convert between common cooking measurement units including cups, tablespoons, teaspoons, fluid ounces, milliliters, liters, pints, quarts, and gallons. Perfect for converting recipes and cooking measurements.

Convert between different angle units including degrees, radians, gradians (gons), and revolutions. Radians are displayed in π (pi) notation when applicable (e.g., π/3, 2π, etc.). Useful for mathematics, physics, engineering, and geometry calculations.

Convert between different pressure units including pascals, kilopascals, bars, atmospheres, PSI (pounds per square inch), torr, and millimeters of mercury. Essential for physics, engineering, and weather applications.

Convert between different energy units including joules, kilojoules, calories, kilocalories, BTU (British Thermal Units), kilowatt-hours, electronvolts, and foot-pounds. Useful for physics, chemistry, and engineering applications.

Convert between different power units including watts, kilowatts, megawatts, horsepower (mechanical and metric), BTU per hour, and foot-pounds per second. Essential for engineering, physics, and energy calculations.

Calculate percentages, percentage increase/decrease, percentage of a number, and what percentage one number is of another. Useful for discounts, tips, statistics, and general percentage calculations.

Convert between fuel efficiency measurements including miles per gallon (MPG), kilometers per liter (km/L), and liters per 100 kilometers (L/100km). Perfect for comparing fuel economy across different measurement systems.

Calculate the duration between two dates. Find out how many days, weeks, months, and years are between any two dates. Useful for planning, age calculations, and tracking time periods.

Note: Months and years are approximations based on average values (30.44 days per month, 365.25 days per year). Days and weeks are exact calculations.

Split a restaurant bill by tracking each friend's items or dividing the total evenly. Add a custom tip, round everyone's share up to the nearest 1, 5, or 10, and display amounts using the currency detected from your current location. You can also scan your bill photo to automatically extract items using OCR technology powered by Tesseract.js.

Calculate discounted prices, savings amounts, and final prices after discounts. Perfect for shopping, sales, and promotional offers. Supports percentage discounts and shows both savings and final price.

Convert between different data storage units including bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), and binary units kibibytes (KiB), mebibytes (MiB), gibibytes (GiB), tebibytes (TiB), and pebibytes (PiB). Decimal units use base 1000, while binary units use base 1024. Useful for understanding file sizes, storage capacity, and data transfer calculations.

Convert between different force units including newtons, kilonewtons, pounds-force, dynes, kilogram-force, and poundals. Essential for physics, engineering, and mechanics calculations.

Convert between different torque units including newton-meters, foot-pounds, inch-pounds, kilogram-force meters, and pound-force feet. Essential for automotive, engineering, and mechanical calculations.

Convert between Roman numerals and Arabic (decimal) numbers. Supports numbers from 1 to 3999. Useful for education, historical dates, and understanding classical numbering systems.

Convert numbers between different number bases including binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16). Essential for programming, computer science, and digital systems.
