ConvBolt — Unit ConverterGrams to Ounces Converter
Converting grams to ounces is a multiplication by a fixed factor: 1 g = 0.03527396 oz. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.
Because one gram works out to 0.03527396 oz, the ounce is the far smaller unit of the two: a figure given in ounce always carries a smaller number than the same measurement in gram. A chart drawn in g can hide that, so check which label the axis uses before you compare two readings.
Where a legal or postal limit is set in ounces, the same limit expressed in grams has to be exact — an overshoot of even one unit can change the chargeable band.
The conversion factor used here is 0.03527396 oz per gram (8 significant digits as shown). Kept to seven figures it covers professional measurement; if you round it to two or three decimals for a spreadsheet, the error scales with the input — at a value of 1,000 g a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 28.34952 g per oz, the exact reciprocal, so a round trip through both pages returns your original number.
