Unit Converter

Select the measurement category (length, weight, temperature, etc.), enter the value you want to convert, choose the source unit and the target unit from the dropdowns. The converted value appears instantly. No button to press — results update in real time as you type.

The Unit Converter supports: Length (km, miles, meters, feet, inches, cm), Weight/Mass (kg, pounds, grams, ounces, tons), Temperature (Celsius, Fahrenheit, Kelvin), Volume (liters, gallons, ml, cups, fl oz), Area (sqm, sq ft, acres, hectares), Speed (km/h, mph, m/s, knots), and Digital Storage (bytes, KB, MB, GB, TB).

Select Length as the category. Enter your distance in the input field, set the source unit to Kilometers, and the target unit to Miles. The conversion appears instantly: 1 kilometer = 0.621371 miles. For example, 10 km = 6.21371 miles.

Select Temperature, enter the Celsius value, and set source to Celsius and target to Fahrenheit. The formula is: F = (C × 9/5) + 32. For example, 37°C (body temperature) = 98.6°F. Conversely, 0°C (freezing) = 32°F.

Select Weight, enter the pounds value, set source to Pounds (lbs) and target to Kilograms (kg). The conversion factor is: 1 pound = 0.453592 kg. For example, 150 lbs = 68.04 kg.

Select Area, enter your square footage, and convert from Square Feet to Square Meters. The factor is: 1 sq ft = 0.092903 sq m. For example, a 1,000 sq ft room = 92.9 sq m.

All conversions use internationally standardized conversion factors (SI units and NIST standards). Results are accurate to at least 6 significant figures, which is more than sufficient for any practical engineering, cooking, travel, or everyday use.

Yes. Full bidirectional conversion between the metric system (SI units) and imperial/US customary units is supported for all categories. Switch source and target units in either direction for instant results.

Yes. The converter is fully mobile-responsive with a touch-friendly interface. The unit dropdowns and number inputs are optimized for use on small screens, with the numeric keyboard appearing automatically on mobile when you tap the input field.

Yes, completely free with no sign-up, no usage limits, and no ads interrupting your workflow. Convert as many values between as many units as you need.
