GCP on there other hand has standardized on unit + nano. They use this for money and time. So unit would 1 second or 1 dollar, then the nano field allows more precision. You can see an example here with the unitPrice field: https://cloud.google.com/billing/v1/how-tos/catalog-api#gett...
Copy/paste the GCP doc portion that is relevant here:
> [UNITS] is the whole units of the amount. For example if currencyCode is "USD", then 1 unit is one US dollar.
> [NANOS] is the number of nano (10^-9) units of the amount. The value must be between -999,999,999 and +999,999,999 inclusive. If units is positive, nanos must be positive or zero. If units is zero, nanos can be positive, zero, or negative. If units is negative, nanos must be negative or zero. For example $-1.75 is represented as units=-1 and nanos=-750,000,000.
Googler, opinions are my own. Over in payments, we use micros regularly, as documented here: https://developers.google.com/standard-payments/reference/gl...
