A roll of new U.S. nickels weighs 200 grams. The roll contains 40 coins, each weighing 5.00 grams each. This measurement requires new coins because some of a coin's metal wears away with handling over time, decreasing the coin's weight. Other common items weighing 200 grams include 1 cup of granulated white sugar or three C-cell batteries.
When baking, measuring ingredients by weight instead of by volume provides greater accuracy in following a recipe. Some common dry ingredients become compacted in ordinary volumetric measuring cups, affecting the amount the cook adds to the dish. Use of an inexpensive digital scale to measure 200 grams of sugar ensures the baker adds the same amount of the ingredient each time he follows a recipe. When converting a recipe from volume measures to weights, bakers must consult a conversion chart, as the weights for different ingredients vary by volume.
When designing portable devices, manufacturers take into consideration the weight added by batteries. The average nickel-metal hydride C battery weighs 67 grams, with three cells weighing 200 grams. Switching to alkaline batteries or rechargeable nickel cadmium batteries does not make a significant difference in the weight. The additional weight of batteries for an item requiring two of these cells is approximately the same as a standard iPhone 6.
