How long is the River Nile in kilometres?

The River Nile is widely recognized as one of the longest rivers in the world, with its length measured at approximately 6,853 kilometers. This measurement accounts for the river's complex journey through multiple countries in northeastern Africa, starting from its primary sources in Uganda and flowing northward through Sudan and Egypt before ultimately emptying into the Mediterranean Sea.

The choice of 6,853 kilometers is the most accurate representation of the river's full length according to various geological surveys and studies. This figure is often cited in educational materials and geographic databases, reflecting the consensus among experts regarding the River Nile's length. The other options, while close in number, do not accurately match the widely accepted measurement, making the selection of 6,853 kilometers not only the correct choice but also supported by extensive research in the field of geography.
