The match will be played at Stockholm's Avicii Arena, where Finland played all seven of their Group A matches, winning six - four in regulation time, one in overtime and one in a shootout - and suffering just one loss, as they finished third in the standings.
They will be hoping the familiar surroundings could be to their advantage up against the Americans, who finished second in Group B, which was played entirely in Herning, Denmark.
But the greater advantage to the Finns could be their playing style, which relies on solid defensive play.
Despite never recording a shutout in the group, they conceded exactly one goal in five of their seven matches, while they are yet to concede more than three in a game, a record equalled only by Canada in the tournament.
Even the forwards in the Leijonat squad know the significance of their defence, including Jan-Mikael Jarvinen, speaking to the IIHF after the 2-1 win over Slovakia to round off the group stage.
“Our system is based on not letting in a lot of goals, that’s key for us. The game against Canada showed that if we believe in our system, we can beat any team.”
The game against Canada was a true nail-biter, in which Finland ended their opponents perfect record in the competition up to that point, and now the task is to down the other great North American hockey superpower, the USA.
Finland scored 22 goals in the group stage, though more than 40% of their strikes came in the 9-1 win over Slovenia. The United States' 34 group stage goals only highlights the need for Antti Pennanen's side to live up to their stingy reputation.
They will also need Juuse Saros to play at his best again - the goaltender has a saving percentage of 95.92 so far, a much better rate than anyone who comes close to the 302 minutes he has spent on the ice.
Waltteri Merala, who opened his goalscoring account for the tournament against Slovakia, was looking ahead to the challenge of the last eight and potentially beyond when speaking to leijonat.fi, "It's starting to open up and now the toughest games are ahead," he said.
"We believe in this thing, anything is possible. This is a top team. I've been involved a lot this season, and it's been an incredibly great journey. I'm looking forward to the playoffs."
