Calculators

Two calculators that run in your browser and store nothing. The rack power calculator checks whether either PDU can carry the whole rack when a feed fails. The tokens per kWh calculator turns tokens per second and watts into tokens per kWh and energy cost per million tokens.

Rack power

Devices per rack, voltage, breaker size and feeds → load per PDU in normal and failover, against the 80 % rule.

Tokens per kWh

Tokens per second, server watts, facility overhead and tariff → tokens per kWh and cost per 1M tokens.
