1km is 1000 meters. 150 million km is 150 000 million meters. 150 000 million meters = 150 billion meters. (Careful I'm talking about 150 with 9 zeroes (150 000 000 000). Billion is the US name for that, but other country's names can vary.)
7 zeros 150 000 000
An average person uses between 6,000 and 10, 000 English words.
150000000000000 150000000000000
150 as a percentage of 1 million = 150*100 / 1 000 000 = 15/1000 = 0.015 %
