* The names and abbreviations of certain units of force conflict with those of certain units of mass. Which is meant can usually be determined
by the context. For example, when it is stated that a Hexapod can tolerate a load of 200 kg vertically, kilograms of force are meant,
but when it is a question of moving a 20 g load at 2 kHz, grams of mass are meant. |
