How do I calculate water pressure using this formula

[From: ] [author: ] [Date: 13-09-25] [Hit: ]
62 kg/m3) (9.80665 m/s2) (29.= 291 146.Is this right? I must have made a mistake somewhere. How do i convert this to the unit Pa?......
I want to know the pressure of a water column (I'm french, not too sure if thats the correct term in english). I was told to use this formula : P = dgh BUT my prof wants units in Pa.
It seems impossible to me to convert my answer in Pa as it has nothing to do with the units I currently have!

Here are the values :

water density : 999.62 kg/m^3

Acceleration due to gravity : 9.80665 m/s^2

Height of the water column : 29.7 cm

So..
P = (999.62 kg/m3) (9.80665 m/s2) (29.7 cm)
= 291 146.82 kg · cm/m2 · s2

Is this right? I must have made a mistake somewhere. How do i convert this to the unit Pa?
Please answer if capable, and thank you so much !

Also, I'd also like to know if it's okay to have gotten water density (accordingly to the temperture of the water) off a website or if i had to calculate it?

THANKS SO MUCH !

Déjà, il faut que tu mette ta hauteur d'eau en mètres (donc tu as h=29,7*10^-3m).

Ensuite, le Newton et le Pascal ne sont pas des unités de base du système international et on peut les convertir en unités de base pour vérifier l'homogénéité

1Pa = 1N.m^-2 (newton par mètre carré) et
1N = 1Kg.m.s^-2.

Donc 1Pa = 1Kg.m.s^-2.m^-2 = 1Kg.m^-1.s^-2.m.

Dans ta formule tu as des Kg.m^-3.m.s^-2.m
Une fois réduit tu obtiens des Kg.m^-1.s^-2 = Pa.
Ton équation est homogène.
