Here's how to express that in minutes:

* 1 minute = 60 seconds

* Acceleration in minutes: (9.81 m/s²) * (60 s/min)² = 353,160 m/min²

Important Note: While technically correct, expressing acceleration in minutes is not common practice. Acceleration is usually expressed in units of meters per second squared (m/s²) because it directly relates to the change in velocity over time.
