==Yield==
The [[Nuclear weapon yield|yields of atomic bombs]] and thermonuclear are typically measured in different amounts. Thermonuclear bombs can be hundreds or thousands of times stronger than their atomic counterparts. Due to this, thermonuclear bombs' yields are usually expressed in megatons which is about the equivalent of 1,000,000 tons of TNT. In contrast, atomic bombs' yields are typically measured in kilotons, or about 1,000 tons of TNT. 

In US context, it was decided during the Manhattan Project that yield measured in tons of TNT equivalent could be imprecise. This comes from the range of experimental values of the energy content of TNT, ranging from {{convert|900|to|1100|Cal/g}}. There is also the issue of which ton to use, as short tons, long tons, and metric tonnes all have different values. It was therefore decided that one kiloton would be equivalent to {{convert|1.0e12|Cal}}.<ref name="contain">{{cite report |date=31 October 1989 |title=The Containment of Underground Explosions |url=https://www.osti.gov/opennet/detail?osti-id=16383760 |publisher=Office of Technology Assessment |page=11 |docket=OTA-ISC-414 |access-date= |quote=}}</ref>
