Frequently Asked Questions

Eight categories: Length (meters, feet, miles, km, inches, etc.), Weight (kg, lbs, ounces, grams, tons), Temperature (Celsius, Fahrenheit, Kelvin), Area (m², ft², acres, hectares), Volume (liters, gallons, cups, ml), Speed (km/h, mph, m/s, knots), Data Size (bytes, KB, MB, GB, TB), and Time (seconds, minutes, hours, days).

Conversions use precise factors with up to 10 significant digits, which exceeds the precision needed for everyday and most professional use. Temperature conversions use the exact formulas (°F = °C × 9/5 + 32, K = °C + 273.15) rather than approximations.

Data size uses binary: 1 KB = 1024 bytes, 1 MB = 1024 KB, 1 GB = 1024 MB. This matches how operating systems (Windows, macOS, Linux) report file sizes. Some storage manufacturers use decimal (1000), which is why a "1 TB" hard drive shows as about 931 GB in your OS.

1 mile = 1.60934 km. So 10 miles = 16.09 km, 100 miles = 160.93 km. The reverse: 1 km = 0.62137 miles. The US uses miles for road distances; almost every other country uses kilometers. Enter any value in either field to convert instantly in both directions.

Select Temperature category, choose Celsius as source and Fahrenheit as target, then type your value. The formula is °F = (°C × 9/5) + 32. Common references: 0°C = 32°F (water freezes), 20°C = 68°F (room temperature), 37°C = 98.6°F (body temperature), 100°C = 212°F (water boils).

Yes. The Swap button reverses source and target units. For example, if you converted meters to feet, clicking Swap converts feet to meters with the same value. Faster than changing both dropdowns manually.

When you select a category and unit, a reference table shows common conversions for that unit all at once. For example, selecting "meters" in Length shows the equivalent in all other length units simultaneously, useful for a quick overview without entering individual values.

Yes, once the page is loaded. All conversion math runs in your browser with JavaScript, no server calls. If you load the page with an internet connection, you can close the network and conversions continue to work.

What Is This Unit Converter?

A quick, no-nonsense tool for converting between units across 8 categories: length, weight, temperature, area, volume, speed, data size, and time. Type a value, pick your units, and get the result instantly.

What It Covers

Metric and imperial units in every category. Miles to kilometers, pounds to kilograms, Fahrenheit to Celsius, terabytes to gigabytes -- the common conversions plus plenty of less common ones. Temperature uses the correct formulas, not simple multiplication.

Common Use Cases

Students doing homework, engineers checking specs, cooks converting recipes, travelers figuring out distances, or developers converting data sizes. If you need a quick unit conversion, this handles it.

Tips

Data size conversions use binary (1 KB = 1024 bytes), which matches how operating systems report file sizes. All results are calculated in real-time as you type.
