How to: Convert Between Metric Prefixes
The Unit Conversion API includes a special converter that helps you convert between different metric prefixes. The following code illustrates how to display a pressure that is equal to 760 millimeters of mercury in hectopascals.
Imports DevExpress.UnitConversion Imports System.Diagnostics ' The pressure value is set to 760 mmHg. Dim pressure As QuantityValue(Of Pressure) = (760).MmHg() ' Since it is a quantity value, it should be transformed to a proper measurement unit ' to obtain a value for display or for comparison. ' The pressure is obtained in Pascals and then converted into hectoPascals. Dim prefixConverter As New MetricUnitsConverter() Dim pressure_in_hPa As Double = prefixConverter.Convert(pressure.ToPascals(), MetricPrefix.None, MetricPrefix.Hecto) Debug.WriteLine(pressure_in_hPa)
