6 AssignmentWhy is a standard international set of units helpful and necessary in science?Should the United States Adopt the Si system of measurement? What changes would this entail? How much would it cost?Convert the Following Units using the stair step method:360cm _____m mm _____m m _____km ,345cm _____da400mL _____L L _____mL dL _____mL kL _____ L934g _____kg kg _____g mg _____g kg _____gCompare using <, > or = to.56cm m g mg mL L mL L43mg g cm m ,445mL L kg gThe ceiling in Mr. O’Connell’s living room is 2.4 m high. He has installed a new hanging lamp that hangs down 61 cm. He is approximately .175dekameters tall. Will he hit his head on the hanging lamp? Draw a sketch and show your work!
