A roll of nickels weighs a little over seven ounces, which is about 200 grams. The United States Mint lists the weight of one nickel as five grams. This number is multiplied by 40 nickels in a roll to get the total weight.
Know MoreBy comparison, a roll of pennies is equal to 2.5 grams times 50 in a roll, which comes to 125 grams or 4.41 ounces. A roll of dimes is 2.27 grams times 50, which comes to 113.5 grams or 4 ounces. A roll of quarters is 5.67 grams times 40, which comes to 226.8 grams or 8 ounces.
Learn MoreTo convert from molecules to grams, it is necessary to first convert the number of molecules of a substance by dividing by Avogadro's number to find the number of moles, and then multiply the number of moles by the molar mass of this substance. Avogadro's number is given as 6.022 x 10^23.

Full Answer >One liter is the equivalent of approximately 0.2642 gallons. As both terms are measurements of volume, one can convert between the two by utilizing the fact that there are about 3.785 liters per gallon.
Full Answer >To convert kN/m2 to kg/m2, multiply by approximately 102 seconds squared per meter, which is 1000/9.8 seconds squared per meter. The conversion of units of force, such as kilonewtons, to units of mass, such as kilograms, assumes that the mass is subject to an acceleration, most often the acceleration of gravity, which is typically around 9.8 meters per second near the earth's surface. However, the precise figure can vary slightly with location.
