I fairly often drive 50,000m/h, except on the autobahn. There I usually go about 120,000,000mm/h.
And if I stack 1000 1cm³ blocks of water, the resulting 10m high column has a volume of 1l, weighs 1kg and exerts 100kPa of pressure on its base. And to heat it by 1°C requires 1kcal, while 1N would accelerate it by 1m/s every second.
What I want to say is: Your point is stupid and your units are too.
