 The cost of all database operations is normalized by Azure Cosmos DB and is expressed by *Request Units* (or RUs, for short). You can think of RUs per second as the currency for throughput. RUs per second is a rate-based currency. It abstracts the system resources such as CPU, IOPS, and memory that are required to perform the database operations supported by Azure Cosmos DB. 
 
-The cost to read a 1 KB item is 1 Request Unit (or 1 RU). All other database operations are similarly assigned a cost using RUs. No matter which API you use to interact with your Azure Cosmos container, costs are always measured by RUs. Whether the database operation is a write, read, or query, costs are always measured in RUs.
