1 kVA (kilovolt-ampere) is equal to 1000 VA (volt-amperes). The relationship between kVA and watts depends on the power factor (PF) of the device or system you're working with.
For a purely resistive load (like a heater or incandescent light), the power factor is 1, meaning:
1 kVA = 1000 watts.
However, for other types of loads (like motors or equipment with a power factor less than 1), the actual wattage will be:
\[ \text{Watts} = \text{kVA} \times \text{Power Factor (PF)} \]
For example, if the power factor is 0.8:
\[ 1 \, \text{kVA} = 1000 \times 0.8 = 800 \, \text{watts} \]
So, the number of watts can vary based on the power factor.
