As is the case in the UK with road signage, the use of metric units in the USA is often hidden from public view. The Apollo Guidance Computer is a good example of this….The Moon landings.

|---|---|---|
| altitude rate | metres per centisecond | feet per second |
| acceleration | metres per centisecond squared | |
| mass | kilograms |
Did NASA use imperial or metric?
Although NASA has ostensibly used the metric system since about 1990, English units linger on in much of the U.S. aerospace industry. In practice, this has meant that many missions continue to use English units, and some missions end up using both English and metric units.
Does NASA use Fahrenheit?
NASA has ostensibly used the metric system since about 1990, the statement said, but English units are still employed on some missions, and a few projects use both. NASA uses both English and metric aboard the International Space Station.

The Apollo Guidance Computer did use metric/SI units internally for its calculations. But it converted to imperial/USC units when it displayed data on the DSKY. This is probably because the Apollo astronauts (mostly trained as test pilots) had an intuitive “feel” for imperial/USC units.
Why do they use nautical miles in space?
The nautical mile is the standard unit of measurement for global navigation distance in most countries(excluding China and Russia). Hence, NASA astronauts are less likely to make mistakes using Knots as opposed to Kilometers or Miles.

The rationale for human exploration of the moon primarily came from a memorandum for Johnson prepared in early May 1961 by NASA Administrator James E. Webb and Secretary of Defense Robert F. McNamara.
