Bhagavad-gita As It Is Lectures

One yuga means forty-three lakhs of years, and multiplied by one thousand, such year, is only twelve hours of Brahmaloka life.

Lecture on BG 3.27 -- Madras, January 1, 1976:

And here within this material world, within this universe, ābrahma-bhuvanāl lokāḥ punar āvartino 'rjuna (BG 8.16). Even if you go to the highest planetary system, Brahmaloka. The Brahmaloka means you cannot calculate one day's life. That is stated in the Bhagavad-gītā. Sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ (BG 8.17). Sahasra-yuga. One yuga means forty-three lakhs of years, and multiplied by one thousand, such year, is only twelve hours of Brahmaloka life. Similarly, twenty-four hours, one month, one year... So it is very, very long duration of life there, where Brahmā lives. But still, you have to die.
