Unit Converter

Frequency & period, storage, data rate, voltage/current and ADC codes — everyday embedded unit conversions in one place.

Frequency ↔ Period

Enter either side and the other is computed live from T = 1/f. Handy for timer ticks, baud clocks and sample rates.

Storage Capacity

Embedded memory and flash are strictly binary: 1 KB = 1024 B = 8192 bit.

Mind the convention: drive and network labels are decimal (1000-based), so a 128 GB stick shows about 119 GB in the OS.

Data Rate

Bit-based units are strictly decimal (1000-based), and bits differ from bytes by 8: 1 KB/s = 8 kbps.

115200 bps UART ≈ 14400 B/s; a 100 Mbps link caps at 12.5 MB/s.

Voltage / Current

1000-based ladders for V / mV / μV and A / mA / μA; results show only the matching dimension.

ADC Code ↔ Voltage

Full scale maps as V = code ÷ (2ⁿ − 1) × Vref, matching the STM32 reference manual.
