How it works

ControlWhat it does
CategoryThe quantity you're converting (voltage, capacitance, energy…).
Value + unitEnter once; every other unit updates instantly.
PrefixesFull SI ladder — p, n, µ, m, (base), k, M, G, T — plus named units (Wh, kWh, mAh…).

Conversions are exact (carried through SI base units), the same dimensional engine that backs the formulas and flows.
