If I have 1.3Kwh at 240V how many amp hour would i have at 12v

In order to get 1.3KWh of energy at 12Volts you would need 108.3Ah

I got a hybrid vehicle battery and the spec is 1.3kwh at 240. I plan on diy the pouch cells into 12v system

Why care about AH? Kwhr is a useful value as it takes voltage out of the equation.

I dont power my fridge by AH, it has a KWhr value.

Why care about AH?

You need to care about Ah when it's time to get batteries. If you know how many kWh you need and the battery voltage, then you can determine the battery capacity (which is almost always shown in Ah).

Other than that detail, I agree that working in Wh is much simpler for most calculations.
