But if none of your readers know what a kellicam is, all you've done is confuse them.
Why? When Torg told Kruge, "Enemy closing on impulse power. Range, 5000 kellicams," it was perfectly clear from context that a kellicam was a unit of distance. When he then counted off "3000 kellicams" and "2000 kellicams," that reinforced his earlier statement that the Enterprise
was drawing closer. I don't see anything confusing there. The viewer didn't have to know what the actual length of a kellicam was in order to understand what was going on there, any more than the viewer has to know the rest mass of a tetryon or what raktajino is made of.
