Hi Suresh,
Thanks for reaching out. The CPC returned from Traffic Estimate service is in micros. To convert it to the values in micros to respective currency you could divide it by 1000000. The microAmount field in the Money type always refers to the account's local currency. Please refer to this documentation for more details on Money fields in report which would be the same for the Google Ads Services.
Please let me know if you have any further concerns.
Thanks and regards,
Xiaoming, Google Ads API Team
