Unit converters for time (s, min, h, day), frequency (Hz, kHz, MHz, GHz), digital data storage (B, KB, MB, GB, TB) and data transfer rate. Covers both SI and binary prefixes for computer science and engineering applications.
Enter a duration in days, hours, minutes and seconds for instant cross-unit display, or paste a Unix timestamp (seconds since 1970-01-01 00:00:00 UTC) to convert it to a human-readable date-time string. Covers the two most common time-handling tasks in programming, scheduling and log analysis.
Type a storage capacity in any unit from bit to petabyte and all eight values refresh at once. Toggle between binary (IEC, base 1024) and decimal (SI, base 1000) prefix conventions — the distinction that explains why a 1 TB hard drive shows as ~931 GiB in Windows. Essential for server sizing, database capacity planning and firmware development.
Enter a HEX colour code (e.g. #1A2B3C) or separate R, G, B values (0–255) and the other format updates in real time, with a live colour swatch for immediate visual confirmation. Useful for web development, UI design and anywhere you need to switch between CSS hex notation and RGB function values.
