Unit Converter

Utilities

Convert between units of length, weight, temperature, and more. Comprehensive metric and imperial converter.

What is This Tool?

A unit converter transforms values between measurement units across categories including length, weight, temperature, volume, area, speed, data storage, and time. Instantly convert between metric, imperial, and other measurement systems with precise calculations.

Unit conversion is fundamental to engineering, science, cooking, travel, and everyday life. This tool covers all major unit categories with accurate conversion factors, handling edge cases like temperature (which uses formulas, not simple multiplication) and data units (binary vs. decimal prefixes).

Common Use Cases

Software Development

Convert between data units (KB, MB, GB, KiB, MiB, GiB), time units (ms, s, min), and CSS units (px, rem, em, vh).

Engineering

Convert between metric and imperial units for international collaboration, specification reviews, and technical documentation.

International Projects

Convert between measurement systems when working with international teams, APIs, or data sources using different units.

Everyday Use

Quick conversions for cooking (cups to ml), travel (km to miles), and health (kg to lbs, °C to °F).

Frequently Asked Questions

What categories are supported?

Length, weight/mass, temperature, volume, area, speed, time, data storage, pressure, energy, and angle measurements.

Is KB 1000 or 1024 bytes?

KB (kilobyte) is 1000 bytes per SI/IEC standards. KiB (kibibyte) is 1024 bytes. This tool supports both conventions and clearly labels which is used.

How is temperature converted?

Temperature uses formulas: °F = °C × 9/5 + 32. K = °C + 273.15. Unlike other conversions, temperature is not a simple ratio.
