A UPS (uninterruptible power supply) sizing calculator determines the required capacity to support IT equipment for a target backup duration. UPS capacity (VA) = total equipment wattage ÷ power factor (typically 0.6–0.8). Runtime decreases as load increases; doubling the UPS capacity roughly doubles runtime.
