300 meters is roughly the height of a very tall skyscraper or just under 1 kilometer. It is also close to the maximum depth rating of many serious diving watches and some submarines.
Basic conversions
- 300 meters is about 984 feet, which is a bit more than three football fields laid end to end in length.
- In nautical terms, 300 meters is around 164 fathoms.
Everyday comparisons
- Many modern “300 m” dive watches are rated for use in serious scuba and mixed-gas diving, showing that 300 meters is considered an extreme but practical working depth for specialized gear.
- Technically advanced submarines often have operating depths in the 200–300 meter range, so 300 meters is on the order of the depth where military submarines routinely work.
In diving context
- In scuba diving, reaching 300 meters is viewed as a kind of “holy grail” of deep diving, and only a handful of divers have ever gone that deep due to the enormous pressure and required decompression.
- At this depth, water pressure is roughly 30 times the air pressure at the surface, which is why only highly trained specialists with special equipment can safely approach it.
