According to Genesis, how long was Noah’s Ark from end to end?

According to Genesis, Noah’s Ark was 300 cubits long from end to end.

Genesis 6:15 gives the vessel’s three principal measurements as 300 cubits in length, 50 cubits in width, and 30 cubits in height. A cubit was an ancient unit commonly associated with the length from an adult’s elbow to the tip of the middle finger, although its exact historical size varied.

Because the cubit was not standardized across all ancient societies, converting the Ark’s measurements into modern metres produces estimates rather than one certain figure. A commonly cited conversion makes the length roughly 137 metres, or 450 feet, but other conversions differ.

These dimensions describe a huge rectangular vessel rather than a ship designed for navigation. The Genesis account emphasizes its capacity and survival during the Flood, while later religious and artistic traditions often portray it with a more conventional boat shape.
