watts and joules

[cte72]

Are joules the same as watts, I ask because I recently got a ipv4s

Watts is final power applied at the coil, or amount of work that is being done.

Joules is similar in a sense but when applied to heating and cooling like British Thermal Units (BTU), Joules measures how much heating is being done over a period of time best I can simplify it down, 10 Watts per second is about equivalent to 10 Joules of watts per second something to that effect. Watts and Joules shake hands so closely in our application or in the application of say heating your home during the winter its kind of hard to sepperate the line between them.

/edit
You are not the only one confused as many have arisen the same question of which is better suited to measure what our atomizers are doing, watts or joules, myself I am leaning toward the Joules side of the camp.

The Watt (W) is a unit for power i.e. the energy used (or supplied) per unit time.

1 J/s (Joule per second) = 1 W (Watt) so yes essentially just a different name in temp control mode

1 watt = 1 joule every second.

it takes something like 1 kilojoule (kJ) to vaporize 1 millilitre (ml) of eliquid.
1 kilowatt (kW) could vaporize 1 millilitre (ml) every second.

Why some tc mods display "J" I do not know

Joules are not the same thing as watts

One Watt of work for one second equals one Joule or 1Watt-second = 1 Joule.

The way they are using the word is incorrect. Just think of it as 'speed of ramp-up' setting. More is faster.

This is 100% correct.

Your ejuice requires energy to be converted from liquid to vapor. Wattage tells you how much of that energy is being applied per unit time.
