Force - Newton (N) N = kg m/s2. Pressure - Pascal (Pa) Pa = N/m2 = kg/(m s2) Rules for Units. When multiplying and/or dividing, you can have different units. The result will be a value that has units corresponding to a product/quotient of the original units. Example 1.
The standard mass of 1 Kilogram (kg) is defined as the mass of a platinum– iridium alloy cylinder (3.9 cm diameter, 3.9 cm height) kept at the International Bureau of Weights and Measures at Sevres, France.
The kinetic energy is given by 1 2 mv2. So if you use the conventional units, it will give 0:5 2500 70 70 lb(mph)2. This quantity of energy needs to be expressed in SI units in this class. So convert the mass into kg and the speed mph into m/s (meter per second). Step 1 Convert mass. It is already done in the above example m = 1134 kg.
