You're describing a conversion factor equal to one (a dimensionless ratio, often just called "1" or "unity").
It's a ratio of equivalent quantities that equals one and is used in dimensional analysis to change units without changing the value. For example:
- 1 = 100 cm / 1 m
- 1 = 60 s / 1 min
- 1 = 2.54 cm / 1 in
You multiply a quantity by one of these conversion factors to convert units while canceling units algebraically.
