How to use this calculator

  1. Enter arrival rate in requests/s.
  2. Enter mean time in system in ms.
  3. Select Calculate and keep the output unit with the answer.

Before you use the answer

Write down whether a size uses decimal or binary prefixes and whether a rate counts bits or bytes. Compare the same system boundary on both sides of a performance calculation. Measured throughput is usually a more useful planning input than the maximum number on a product label.

Use matching boundaries and long-run averages; overloaded transient systems violate the simple steady-state interpretation.

Why might a result be approximate?

Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
