Technically, it depends on where he weighs 1000 newtons, which isn't specified.
I mean, if he weighs 1000 newtons on the moon, then his mass is 625 kilograms.
We're going to make a big assumption here, and assume that he weighs 1000 newtons
on or near the surface of the earth. In that case, his mass is 102 kilograms . (rounded)
Mass is a characteristic of the person or object. It stays with him/it and doesn't change no matter where he/it goes. "Newtons" is not a measurement of mass. It's a measurement of force, and it could represent the person's weight. If the person weighs 490 newtons on Earth, then his mass is about 50 kilograms anywhere, and he would weigh about 81 newtons on the moon.
250 Newtons converted into mass is 25.5 kilograms
The rock's mass on earth will be 5kg (mass = force in newtons / 9.807)
'Kg' is a unit of mass, not weight. On Earth, 1 kg of mass weighs 9.8 newtons, and 1 newton is the weight of about 0.102 kg of mass. On the moon, the same kg of mass weighs 1.6 newtons, and 1 newton is the weight of about 0.616 kg of mass. On Mars, the same kg of mass weighs 3.7 newtons, and 1 newton is the weight of about 0.269 kg of mass.
If it weighs 98 newtons on Earth, then we know that its mass is about 10kg. If that figure is its weight somewhere else, then its mass is something else.

43.10 newtons because weight affect newtons
A one kilogram mass weighs 9.81 Newtons

1 kg of mass weighs 9.81 newtons on Earth and 3.7 newtons on Mercury.
On or near the Earth's surface, 62 kg of mass weighs 608 newtons (136.68 pounds).
4.9966kg
On earth, a mass of 5.306 kilograms weighs 52 newtons. That's some baseball ! More like a bowling ball.
On earth the rock has a mass of 9.6kg
