This is important to the Ketchup:Gasoline ratio of 1:3. Ketchup being about $3 per litre compared to $1 per litre for gasoline.

A potential tomato war would bring the ratio to as high as 1:4.5, or $4.50 per litre for Ketchup. Ketchup of course being far far more rare and valuable than gasoline, everyone has to eat afterall.

What is the ketchup: gasoline ratio if we use density, as I think a KG of ketchup would be cheaper then a KG of gas?

What about Mustard as an alternative to Ketchup? I've gotta assume as the price of Ketchup rises more and more consumers will look to mustard as a cheaper alternative, Mustard is very much the diesel of condiments .
