Understand the context of your measurement to select appropriate units
-
Apply conversions mainly for comparative analysis rather than direct measurement
Limitations
-
Handling extremely large numbers which may exceed typical instrument ranges
-
Conversion may be mainly theoretical and not practical for direct measurements
-
Precision and unit appropriateness must be considered carefully in conversions
Frequently Asked Questions
