Answer:
Metric unit is for measurement and place value units is for numbers.
They are alike because one kilometer is equal one thousand times more than one meter like one thousand is equal to one thousand times more than one one.
That is we can say
1 kilometer= 1,000 x 1 meter
1 thousand=1,000 x 1 one
1 Liter= 1,000 x 1 milliliter
1 ten thousand=1,000x 1 ten
1 Kilogram=1,000 x 1 gram
1 hundred thousand=1,000 x 1 hundred
They are different because metric units are for measurement/volume/mass and place value units are for counting/numbers.
