The Nets announced the deal in a statement released Wednesday afternoon.
"Marcus is a proven scorer in this league," Nets general manager Billy King said in the statement. "He is a young talent who will help us in the backcourt."
Thornton took to Twitter on Wednesday afternoon to thank the Kings and look ahead to the Nets.

Sources told ESPN.com that the Nets' first choice was to trade for Cleveland's Jarrett Jack. But the Cavaliers' reluctance to take Terry scuttled those talks. The Nets then turned their attention to Thornton, who is having a down season with Sacramento. The Nets hope he can provide some added offensive punch off the bench.
The Akron Beacon Journal reported earlier Wednesday that the Thornton trade was nearing completion.
Thornton is averaging 8.3 points per game and 38.1 percent shooting this season. In 2010-11, he averaged 21.3 points and followed that up by averaging 18.7 points in 2011-12.
In his first season with the Nets since coming over in the Paul Pierce and Kevin Garnett trade during the summer, Terry has averaged 4.5 points in 35 games. The 6-foot-8 Evans, known for his rebounding, has appeared in 30 games and is averaging 2.7 points and 5.0 rebounds. He averaged 11.1 rebounds in 80 games last season.
Sources told ESPN.com that the Nets are also trying to complete a trade with the Los Angeles Lakers in which they would take Jordan Hill into their $5.25 million disabled player exception for Brook Lopez.
The Nets, sources said, are prepared to complete the deal, despite the fact that adding Hill in this manner will add more than $15 million to this season's payroll and take it beyond the $200 million mark. Sources say the Lakers haven't yet committed to deal him to Brooklyn, and both Phoenix and Dallas have inquired about Hill, according to a league source.
Hill, who has found it difficult to receive consistent playing time in Lakers coach Mike D'Antoni's rotation, said he wants to stay in L.A. but wants a bigger role.
"I'm having a ball here, but when I'm here, I do want to play," Hill said. "I love my teammates, I love the coaching staff, I love everybody [with] the Lakers. I've had a great time here, if anything does happen."
