What is the formula used for converting data to strain in the NI-DAQ method:
public AIChannel CreateStrainGageChannel(string physicalChannelName, string nameToAssignChannel, double minimumValue, double maximumValue, AIStrainGageConfiguration strainGageConfiguration, AIExcitationSource voltageExcitationSource, double voltageExcitationValue, double gageFactor, double initialBridgeVoltage, double nominalGageResistance, double poissonRatio, double leadWireResistance, AIStrainUnits units);

The formula depends on the strain gage configuration you select. Here is a White Paper that overviews the available strain gage configuration options and the associated formulas:
