Let’s get something out of the way. It would not be possible for a person to stand on the Sun. Leaving aside the fact that you’d be fried by the heat way before reaching it, even if you had a way to protect yourself the Sun does not have a solid surface so it would not be possible to walk on it. Just like on a gas planet, you would just “fall” and sink into its core until you were disintegrated by the heat and the pressure.
But for the sake of answering the question, let’s say that you could find a futuristic spacesuit that would somehow allow you to “stand” on top of it.
In that case, how much would you weigh on the Sun?
In the Sun, you would weigh almost 28 times your current weight on Earth. This means that a person that weighs 70 kilograms (154 lbs) on Earth would weigh approximately 1,950 kilograms (4,300 lbs) on the Sun.
On top of that, you would need to carry the weight of the protective suit that would help you survive. And the weight of that suit would also be increased.
To give you an idea of how heavy astronaut suits are, the spacesuits that the Apollo astronauts used to walk on the Moon weighed about 163 kilograms (360 pounds) on Earth. Thankfully, on the Moon that weight was reduced to just 27 kilograms (60 pounds) which is still a lot, but it is manageable. On the Sun, the complete opposite would happen and that suit would weigh more than 4.5 tons.
To precisely calculate your weight on the Sun you can use a simple rule of three that factors in the difference between the force of gravity on both planets.
The following calculator simplifies the process.

Weight on the Sun formula
The formula to calculate your weight on the Sun is as follows:
WSun = (WEarth / 9.81) * 274
WSun: Weight on the Sun
WEarth: Weight on Earth
The other two numbers are the force of gravity on each planet and it is given in meters per square second (m/s2). The force of gravity on Earth is 9.81 m/s2 and on the Sun, it is approximately 274 m/s2.
