Choose a quantity, enter a value, and compare equivalent values across its units. Keep the physical quantity and unit definition consistent.
For example, 1 bar = 100,000 Pa = 100 kPa. Similarly, 2 kWh × 3,600,000 J/kWh = 7,200,000 J.
Only when they measure the same physical quantity. Converting dynamic viscosity into kinematic viscosity requires density; changing units alone cannot supply it.
Premature rounding can accumulate error. Keep sufficient intermediate precision and round the final result to match the precision of the original measurement.
