Convert mW, W, kW, HP, dBm, and dBW. Covers both mechanical and RF/signal power measurement.
Convert N·m, kN·m, ft·lbf, in·lbf, and kgf·m. Useful for robotics, motor sizing, and mechanical assembly specs.
Convert Pa, kPa, MPa, bar, psi, atm, and mmHg. Handy for thermal management, fluid systems, and pneumatic specs.
Convert N, kN, lbf, kgf, and dyne. Used in structural analysis, connector force specs, and actuator calculations.
Convert pF through F. Includes inductance conversion (nH → H) for filter and oscillator design work.
Convert J, kJ, cal, kcal, Wh, kWh, eV, and BTU. Covers everything from battery capacity to semiconductor physics.
All converter results update in real time as you type. Click any value to copy it, or use the copy button in each card.
Day-to-day hardware and software engineering involves a constant stream of unit conversions. A CPU datasheet lists a core clock in MHz but your software works in GHz. A resistor tolerance is in kΩ but the PCB label shows Ω. A motor spec gives torque in N·m but you need ft·lbf for a vendor's table. This Dev Converter handles all of those in one tool — no ads, no popups, and no need to search across multiple sites.
The Frequency tab converts between Hz, kHz, MHz, GHz, and THz in real time. It also includes a clock period calculator — enter a frequency in MHz and instantly see the cycle time in nanoseconds, microseconds, and milliseconds. This is directly useful when verifying timing constraints, reading UART baud rates, working with oscillator specs, or setting up PWM parameters in firmware.
The Voltage tab converts between millivolts, volts, and kilovolts, with common SoC and PCB reference values shown. The built-in Ohm's Law helper lets you enter any two of voltage, current, and resistance — the third is calculated automatically along with the power dissipation in watts. This saves time when sizing resistors, checking voltage dividers, or verifying a power budget.
One of the most common sources of confusion in networking and storage work is the difference between bit-based and byte-based speed units. This converter handles bps, Kbps, Mbps, Gbps on one side and KB/s, MB/s, GB/s on the other — converting between them correctly (1 byte = 8 bits). The download time calculator lets you enter a file size and connection speed to see an estimated transfer time in seconds, minutes, or hours.
