Joule
As energy is defined via work, the SI unit of energy is the same as the unit of work – the joule (J), named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units
Ampere
The SI unit of electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter.
140 degree Fahrenheit
F-32=(C/100)*180
F=((C/100)*180)+32
F=(60/100) * 180) +32
=(108)+32
F = 140 degree Fahrenheit
Temperature
The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. t= T- T0. t/°C = T/K - 273.15.
