That brings the total number of civilians unintentionally killed by the coalition since the start of operations against the militant group in 2014 to 220, the military said in a statement.
"Although the Coalition takes extraordinary efforts to strike military targets in a manner that minimizes the risk of civilian casualties, in some incidents casualties are unavoidable," the statement said.
The military estimate is far lower than those provided by monitoring groups.
In an incident on Jan. 13, near the Iraqi city of Mosul, the military said eight civilians were killed during a strike on Islamic State fighters in a house.
As of Feb. 28, the coalition has carried out 18,666 strikes in Iraq and Syria since the start of the operation, according to U.S. military data. The average daily cost of operations is $12.7 million, according to the data.
