Chapter 1, Problem 104c
Which is larger in each pair, and by approximately how much? (c) A gram or an ounce
Verified step by step guidance1
Understand the units involved: A gram is a metric unit of mass, while an ounce is an imperial unit of mass.
Recall the conversion factor between grams and ounces: 1 ounce is approximately 28.35 grams.
To compare a gram and an ounce, consider how many grams are in one ounce.
Since 1 ounce is 28.35 grams, an ounce is larger than a gram.
Calculate the difference by subtracting 1 gram from 28.35 grams to find out how much larger an ounce is compared to a gram.

Approximation in Measurements
When comparing measurements, it's important to understand that approximations can simplify calculations. In this case, one can round the conversion factor to 28 grams per ounce for easier mental math, which still provides a clear understanding of the relative sizes of the units.
