All Conversion Categories
M-Convert organizes 200+ converters into twelve practical categories. Every tool is fully functional, uses verified conversion factors, and works entirely in your browser.
Basic Conversions
Length, weight, volume, temperature, area, time, speed, pressure, energy, power, and more.
20 toolsComputer & Digital
Data storage, transfer speed, number bases, ASCII, DPI, timestamps, and pixel conversions.
20 toolsElectrical & Electronics
Voltage, current, resistance, capacitance, inductance, charge, and magnetic fields.
15 toolsScience & Physics
Viscosity, entropy, radiation, photometry, molarity, and other advanced physical quantities.
25 toolsConstruction & Engineering
Concrete, rebar, board feet, slope, stress, strain, gear ratios, and pressure head.
20 toolsCooking & Food
Cups, grams, milliliters, tablespoons, ounces, butter, flour, sugar, and cooking temperatures.
10 toolsGeography & Weather
Nautical miles, knots, coordinates, time zones, rainfall, snowfall, and altitude.
15 toolsFashion & Lifestyle
Shoe sizes, clothing sizes, ring sizes, fabric GSM, thread count, and typography units.
15 toolsAutomotive & Transport
Fuel economy (MPG, L/100 km, km/L), horsepower, torque, tire pressure, and engine displacement.
15 toolsMedical & Chemistry
Blood glucose, cholesterol, molarity, molality, ppm, ppb, pH, and dosage units.
15 toolsMathematics
Fractions, decimals, percentages, ratios, logarithms, bases, and Roman numerals.
15 toolsAstronomy & Advanced

15 toolsHow Categories Work
Each category collects tools that share a domain. Within a category, individual converters are grouped by dimension or by function — for example, the Basic Conversions category contains dedicated pages for length, mass, volume, temperature, area, time, speed, pressure, energy, power, force, torque, density, frequency, acceleration, and flow rate.
Every converter page follows the same structure: a direct answer at the top, a working calculator, the formula with variable definitions, worked examples, a common-values table, real-world uses, unit definitions, accuracy notes, related converters, and FAQs. This consistent layout makes any page usable within seconds, whether you are a student, engineer, chef, or traveler.
Finding a converter
- Use the homepage search for immediate answers — type "km to miles" or "celsius to fahrenheit".
- Browse All Tools for a full directory.
- Use the A–Z Index if you know the exact conversion name.
- Open a category below if you prefer to explore by topic.
