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.
Given a starting unit in kN, or kilonewtons, multiply by 1000 to get the corresponding number of newtons. One newton is a kilogram meter per second squared, and a kilonewton is 1000 kilogram meters per second squared.
According to Newton's second law, F=ma, which is to say that force is the product of mass and acceleration. This can be algebraically rearranged to m = F/a, or mass equals force divided by acceleration. The precise acceleration due to gravity varies with latitude, altitude and local geology.
When a newton, or kilogram meter per second squared, is multiplied by a second squared per meter, the reciprocal of acceleration, the seconds and meters cancel out, and only the kilogram term is left. Since the per square meter quotient of the original is unchanged, the answer is expressed in the desired units.
Converting from pounds to kilograms involves finding the conversion factor of 0.45 kilograms/pound and using this to create a conversion equation. Solving the equation (270 pounds)(0.45 kilograms/pound) supplies the answer of 121.5 kilograms.
Full Answer >Fifteen kilograms is equal to approximately 33.069 pounds. Since there are exactly 2.2046 pounds in 1 kilogram, simply multiply the value in kilograms by 2.2046 to obtain the value in pounds.
Full Answer >A bomb calorimeter is used to determine the enthalpy of combustion of hydrocarbons. Bomb calorimeters are constant volume calorimeters that are used to determine the energy necessary for certain hydrocarbons to undergo a combustion reaction.
Full Answer >Power in watts equals amperes times voltage. So, in a direct current, 1 amp at 110 volts equals 110 watts, whereas 1 amp at 220 volts equals 220 watts.
