Compare keyboard switch actuation force and typing effort over a day.
Typing work is force multiplied by travel distance and keystroke count, so a 15 gram difference compounds measurably across eight thousand keystrokes. Actuation distance matters as much as force. The absolute energy is small, but the repetition is what makes switch weight a comfort decision for anyone typing all day.
