Explain the units and how to solve the following metric convertion then solve the metric conversion by filling in the blank 12 km = m,

Kilometre and meter both are the units which is used to determine the length.

Kilometre and meter both are the metric measurement and abbreviated as km and m. Conversion of km into m include the multiplication of length with the conversion ratio. 1 km is equal to 1000 m. Thus, by multiplying with 1000, given length in km can be converted to m.

Since, 1 km = 1000 m.

Then, 12 km = m

= 12000 m.

Hence, 12 km = 12000 m

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
