Solution. To convert kB to MB, use the conversion factor. 1 MB = 1,000 kB. then divide both sides of the equation by MB, to get the conversion ratio. 1 = 1,000 kB / MB. Use the conversion ratio to complete the unit conversion, basically dividing the input by 1, the kB units cancel out, and we are left with MB units.
