As per their 'Strength Scale' report, Spider-Man (Peter Parker) can move around/hold up a minimum of 10 tons while Captain America (Steve Rogers) stresses out beyond 1200lbs.
Like his namesake, Spider-Man's strength and agility stand far above those of the average human, allowing him to lift nearly ten tons and to leap and move at incredible speeds with high accuracy.
In a death battle? Spider-Man should definitely win. He's faster, stronger, tougher, quicker, and has more options at range. On top of that he has his Spider-Sense to help warn him of dangers.
Captain America and Spider-Man are on a similar level in many ways, but if it came to a fight between them, Spider-Man would ultimately win against Captain America due to his slightly better abilities and superior powers.
According to official Marvel Database, Captain America's full limits of strength is lifting up to 1,200 lbs with maximum effort, which gives him the ability to knock out Thunderball who possessed superhuman durability and also lift merge hulk.

Strength. Captain Marvel can lift 200 tons when in Binary mode—a hefty 400,000 pounds that is well over the combined lift of Cap, Iron Man, Widow, Black Panther, Scarlet Witch, Vision, Ant-Man, the Wasp, Doctor Strange, and Hawkeye.
Thor. Blessed with the powers and long life of a god, Thor was undoubtedly the most powerful member of the initial version of the Avengers. Not only can he fly and transport between worlds, but he was also the only one capable of taking down Thanos, even after he had assembled all six Infinity Stones.
Spider-Man may be one of the strongest Marvel heroes around, but Captain America was still the best soldier alive. Cap's experience always beat Spider-Man's raw strength.
UNLIMITED STRENGTH
The answer; there isn't one. The amazing thing about the Hulk is that unlike nearly every other superhero ever created, the Hulk's strength has absolutely no upper limit. He can lift a commercial airplane – which weighs around 100 tons – when he is at his calmest; that's no problem for him.

With everything said, Captain America is much slower than Spider-Man, and he would certainly not be able to win against him in any speed-related contest.
Spider-Man is already significantly stronger than Wolverine, meaning that if there are any bodies of water around the pair when they fight, Logan's already a goner, but even if not, Spider-Man also carries around a rapid-setting adhesive that could cut off Wolverine's oxygen if Spidey was prepared to get in close.
According to his official Marvel page, Spider-Man is capable of lifting up to ten tons, and that means that he is a lot stronger than some of the other characters that have peak-human strength. However, Spider-Man's strength pales in comparison to the likes of Thor and the Hulk.

Even without the Infinity Gauntlet, Thanos has proven himself to be a hugely powerful threat, often taking on entire teams of Avengers at once. However, it is with the Infinity Gauntlet that he can most consistently defeat the Avengers.
