Google Ads Currency and Monetary Values

The Google Ads API uses micros for all monetary values. This is done to prevent rounding errors when working with floating point numbers.

Micros

All monetary metrics with the _micros suffix are represented in micros of the account's base currency:

1 micro = 1/1,000,000 of the base currency unit

Conversion Formula

real_value = micros_value / 1_000_000

Examples

Micros	Real amount
1,000,000	1.00
5,000,000	5.00
500,000	0.50
10,000	0.01
100,000,000	100.00

Fields in Micros

Field	What it measures
metrics.cost_micros	Total cost
metrics.average_cpc	Average cost per click
metrics.average_cpm	Average cost per 1000 impressions
metrics.cost_per_conversion	Cost per conversion
metrics.conversions_value	Conversion value
campaign.budget_amount_micros	Campaign budget
ad_group.cpc_bid_micros	Ad group CPC bid
ad_group.target_cpa_micros	Target CPA

Account Base Currency

The account currency is set at creation and stored in customer.currency_code:

Code	Currency
USD	US Dollar
EUR	Euro
RUB	Russian Ruble
GBP	British Pound
JPY	Japanese Yen
...	...

LightLead displays data in the account currency. Multi-currency conversion (when accounts in different currencies are present) is performed at the LightLead level using current exchange rates.

Conversion in LightLead

LightLead automatically converts micros to real currency:

function convertMicros(micros: number): number {
  return micros / 1_000_000;
}

All amounts shown in the LightLead interface are already in real currency, rounded to 2 decimal places.

Rounding

During Aggregation

Rounding errors are possible when summing values. LightLead uses banker's rounding:

• 1.005 → 1.00
• 1.015 → 1.02

In Reports

For precise financial calculations, it's recommended to:

1. Use raw values in micros
2. Convert to real currency only at the final step
3. Compare totals against Google Ads data (micros provide high precision)
