Metric unit for Throughput and the Latency

What is the unit for Latency in vSAN? I am using healthPort.vsanPerfQueryPerf() method call to get the performance metrics and the latency metric value is 1000 times more than the value in vCenter. In vCenter metric unit is ms.

And, what is the Throughput(IOPS Read/Write) unit in vSAN? There is a discrepancy in throughput values in vCenter and vSAN.
