**How to convert kVA to amps**

You can calculate amps from
kilovolt-amps and volts,
but you can't convert kilovolt-amps to amps since kilovolt-amps and amps
units do not measure the same quantity.

**Single phase kVA to amps calculation formula**

The current I in amps is equal to
1000 times the apparent power S in kilovolt-amps, divided by the voltage V in
volts:

*I*

_{(A)}= 1000 ×

*S*

_{(kVA)}

*/*

*V*

_{(V)}

So amps are equal to 1000 times
kilovolt-amps divided by volts.

amps = 1000 × kVA / volts

or

A
= 1000 · kVA / V

**Example**

Question: What is the current in
amps when the apparent power is 3 kVA and the voltage supply is 110 volts?

Solution:

*I*= 1000 × 3kVA / 110V = 27.27A

**3 phase kVA to amps calculation formula**

The current I in amps is equal to
1000 times the apparent power S in kilovolt-amps, divided by the square root of
3 times the line to line voltage V in volts:

*I*

_{(A)}= 1000 ×

*S*

_{(kVA)}

*/ (*

*√*3 ×

*V*

_{(V)}

*)*

So amps are equal to 1000 times
kilovolt-amps divided by the square root of 3 times volts.

amps = 1000 × kVA / (

*√*3 × volts)
or

A
= 1000 · kVA / (

*√*3 × V)**Example**

Question: What is the current in
amps when the apparent power is 3 kVA and the voltage supply is 110 volts?

Solution:

*I*= 1000 × 3kVA / (

*√*3 × 110V) = 15.746A

**How to convert amps to kVA**

You can calculate kilovolt-amps from
amps and volts,
but you can't convert amps to kilovolt-amps since kilovolt-amps and amps units
do not measure the same quantity.

**Single phase amps to kVA calculation formula**

The apparent power S in
kilovolt-amps is equal to current I in amps, times the voltage V in volts,
divided by 1000:

*S*

_{(kVA)}=

*I*

_{(A)}

*×*

*V*

_{(V)}

*/ 1000*

So kilovolt-amps are equal to amps
times volts divided by 1000.

kilovolt-amps = amps × volts / 1000

or

kVA
= A · V / 1000

**Example**

What is the apparent power in kVA
when the current is 12A and the voltage supply is 110V?

Solution:

*S*= 12A × 110V / 1000 = 1.32kVA

**3 phase amps to kVA calculation formula**

The apparent power S in
kilovolt-amps is equal to current I in amps, times the line to line voltage V
in volts, divided by 1000:

*S*

_{(kVA)}=

*√*3 ×

*I*

_{(A)}

*×*

*V*

_{(V)}

*/ 1000*

So kilovolt-amps are equal to amps
times volts divided by 1000.

kilovolt-amps =

*√*3 × amps × volts / 1000
or

kVA
=

*√*3 × A · V / 1000**Example**

What is the apparent power in kVA
when the current is 12A and the voltage supply is 110V?

Solution:

*S*=

*√*3 × 12A × 110V / 1000 = 2.286kVA
