The Mars Climate Orbiter incident In 1999, when NASA's Mars Climate Orbiter spacecraft was lost in space due to a software error.
The software on the spacecraft used metric units, while the ground-based navigation software used imperial units. This mismatch in units led to incorrect calculations and caused the spacecraft to approach Mars at the wrong trajectory.

❌ Your types should never be "Int" or "String"
✅ Use instead "Duration", "Length", "DateTime" ...

Also the metric system is objectively better than imperial units.
