Frequently Asked Questions
What is the difference between scientific and engineering notation?
In scientific notation, the exponent can be any integer so the mantissa is between 1 and 10. In engineering notation, the exponent is always a multiple of 3 (e.g. 10^3, 10^6, 10^-6), aligning with metric prefixes like kilo, mega, and micro.
What are significant figures?
Significant figures are the digits in a number that carry meaningful precision contributing to its measurement resolution.
