Here you must calculate 1 / 0.365.
1 Newton is 1 joule/meter.
The equivalent of about 6,330,000,000 joules or 6 million BTUs
It is approx 3.82*10^26 Joules.
One foot-pound of force equates to about 1.355818 joules.
Kilo is the prefix for one thousand. So, 3,872.8 joules is 3.8728 kilojoules.
1 calorie = 4,18400 joules
