A car on average weighes about 1000 kilos a fair few weigh more and some weigh less. So the number of cars needed would be somewhat less than 10 billion
There are 3,500,000 short tons in 7 billion pounds.
The number of cars that make up 7 tons depends on the weight of each car. For example, if an average car weighs about 1.5 tons, then 7 tons would be equivalent to approximately 4 to 5 cars. However, if the cars are smaller or larger, the number may vary accordingly.
4 billion pounds equates to 1,814,400 tonnes.
2,000 pounds = 1 ton 200 billion pounds = 100 million tons
Approximately 1.9 billion metric tons of iron are produced globally each year.
One billion (1,000,000,000) pounds = 500,000 US Tons 446,000 UK Long Tons 454,000 Tonnes (Metric Tons)
2 billion half tons
4,000,000,000,000
650 billion of them.
Exactly 4.0389
12,000,000,000,000,000 lbs
1 Gt = 1 billion tons (1,000,000,000 tons) 1 Mt = 1 million tons (1,000,000 tons) 1 billion ---------- = 100 Mt in per Gt 1 million
