Label method for converting units (dimensional analysis) label method of unit a very useful method of converting one unit to an equivalent unit is called the factor conversion. you may be given the speed of an object as 25 km/h and wish to express it in m/s. to make this conversion, you must change km to m and h to s by multiplying by not want will cancel out and the units you want will emain, conversion factors: 1000 m -1 km and 3600 a series of factors so that the units you do seconds# 1 hour do the following conversions using t he factor-label method. include units in each step and box in your 7. how many meters are in 100 feet?
