Hi,
Thank you for reaching out to the Google Ads API team.
In Google Ads API perspective, if you are referring to cost data, please note that Fields of type Money are returned in micro currency units (micros) in the API which means for example, 1.23 would be converted to 1230000 (multiply by 1000000). To have the same metrics.cost_micros as the console/UI you could simply divide the cost by 1000000.
Additionally, you may check this
Type and format summary guide, for more information about this.
