- Zeros between non-zero digits are significant.
- Leading zeros are not significant.
- Trailing zeros in a number containing a decimal point are significant.
Calculations with Significant Figures:
- When multiplying or dividing, the result should have the same number of significant figures as the measurement with the fewest significant figures.
- When adding or subtracting, the result should have the same number of decimal places as the measurement with the fewest decimal places.

When converting gallons to liters, it is important to consider the number of significant figures in the original measurement and maintain that level of precision in the converted value. For example, if you are converting 3.0 gallons to liters, the result should be rounded to two significant figures (11 liters) to reflect the precision of the original measurement.

Using the correct number of significant figures ensures that the converted value accurately represents the precision of the original measurement and avoids overstating the accuracy of the result. This is particularly important in scientific and engineering applications where precision is paramount.
