Older helicopters such as the Whirlwind and Wessex have gauges marked in Ft/lbs.
But then as long as there is a clearly marked limit and you don't go over it, what do units matter to the pilot?
The Puma HC1 didn't have torque gauges at all, only a main rotor collective pitch gauge. The CP limits changed with the flight regime and that meant you had to know the graph!
