One converter for everyday and technical units
Switch between length, mass, temperature, area, volume, speed, time, energy, power, pressure, frequency, and data storage. Each category offers several commonly used units, including imperial, metric, and engineering measurements.
Conversions use defined unit factors where available. Temperature uses scale offsets, and digital storage distinguishes decimal (kB, MB, GB) from binary (KiB, MiB, GiB) units. Results are rounded for display, not during calculation.
