Sigfig with double dimensional analysis

Front

What are significant figures (sig figs)?

Back

Significant figures are the digits in a number that contribute to its precision. This includes all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion.

Front

How do you determine the number of significant figures in a measurement?

Back

Count all non-zero digits, any zeros between them, and trailing zeros in a decimal number. Leading zeros are not counted.

Front

What is dimensional analysis?

Back

Dimensional analysis is a mathematical technique used to convert units from one system to another, ensuring that the equations are dimensionally consistent.

Front

How do you apply dimensional analysis to solve problems?

Back

Identify the units you have and the units you need, then multiply by conversion factors that relate the two until you reach the desired unit.

Front

What is the rule for addition and subtraction with significant figures?

Back

The result should be reported with the same number of decimal places as the measurement with the least number of decimal places.

Front

What is the rule for multiplication and division with significant figures?

Back

The result should have the same number of significant figures as the measurement with the least number of significant figures.
