容量 (róng liàng): capacity

This water cup has a capacity of 500 milliliters, which is enough for me to drink all morning.

This restaurant is full every night, but its capacity is only thirty seats, so people often have to queue.

My phone's memory capacity is insufficient, so I need to delete some photos and videos.

This stadium has a large capacity; it can hold fifty thousand people watching a game at the same time.

The suitcase's capacity is limited; you can only take the most important things for your trip.
