Getting a feel for the scale
A converted number is easier to trust when you can picture it. These reference points let you sanity-check the result at a glance.

- A slice of bread is about 1 oz
- A tennis ball is roughly 2 oz
Gram (g)

Common mistakes to avoid
- Dividing when you should multiply. Because 1 ounce = 28.3495 grams, the answer should be larger than the number you started with.
- Confusing the fluid ounce (a volume) with the ounce (a weight). They are different quantities and only coincide for water by rough approximation.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
Kitchen scales resolve to about 1 g or 0.1 oz, so two significant figures beyond the decimal point is wasted precision. Postage and freight are normally rounded up to the next billing increment.
How these units are defined
- Ounce (oz): The avoirdupois ounce: one sixteenth of a pound. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
- Gram (g): One thousandth of a kilogram; the everyday metric mass unit. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
