Duty cycle of fuel injectors

Is the duty cycle (ON time relative to OFF time) of fuel injectors directly proportional to fuel being used by the engine?

In other words, if I can see a 10% ON time of my injectors on an o'scope can I assume that when it shows a 20% ON time that it is using twice as much fuel per unit of time?
