What is the minimum number of significant figures required for a numerical answer to always meet a 1% tolerance level?

The typical 'rule of thumb' is that for a numerical answer to always meet a 1% tolerance level, it must have a minimum of 3 significant figures. An example of a number with 3 'sig figs' is 121.

Numerical tolerance level is the tolerance level which determines that the level of error accepted.

The minimum number of significant figures required for a numerical result to always meet a 1% tolerance level is 3%.

What is numerical tolerance level?

Numerical tolerance level is the tolerance level which determines that the level of error accepted.

Significant figures-

The significant figure is the figure which is used to express the each digits of a number to the required degree of accuracy.

If a number which has 3 digits and all the degree of all the digits is accurate.Thus the tolerance level is one percent.

Hence, the minimum number of significant figures required for a numerical result to always meet a 1% tolerance level is 3%.
