Kilovolt-amp (kVA) kVA is kilo-volt-ampere. kVA is a unit of apparent power, which is electrical power unit. 1 kilo-volt-ampere is equal to 1000 volt-ampere: 1kVA = 1000VA. 1 kilo-volt-ampere is equal to 1000 times 1 volt times 1 ampere: 1kVA = 1000â1Vâ1A. kVA to volt-amps calculation.
Carcinoembryonic antigen (CEA) is a protein that is found in many types of cells. It is associated with tumors or a developing fetus. Blood levels of this protein disappear after birth. In adults, CEA may be a possible sign of cancer. The CEA test is performed to monitor the severity of cancer or tumors in the patients.
