Order of Magnitude
A class of scale or size used to compare quantities, typically expressed as a power of ten.
Sensible Estimate
A rough calculation or approximation that is reasonable and based on known values or assumptions.
Approximate Value
A value that is close to the actual amount but not exact, used for quick calculations or checks.
Order of Magnitude

Sensible Estimate
A rough calculation that provides a reasonable approximation of a physical quantity based on known values and assumptions.
Approximate Value
A value that is close to the actual amount but not exact, used to simplify calculations and check the realism of results.
estimated value
