# What is the Dimensional Formula of Pressure?

Posted in Dimensional Formulae | Email This Post |Pressure is defined as force per unit area.Mathematically its formula is

**Pressure = Force/Area**

Now, we have already derived the dimensional formula for force and area in previous posts. So

Dimensional Formula of Force= M^{1}L^{1}T^{-2}

Dimensional Formula of Area= M^{0}L^{2}T^{0}

Thus

Dimensional Formula of Pressure = (M^{1}L^{1}T^{-2})/(M^{0}L^{2}T^{0})

**Dimensional Formula of Pressure = M ^{1}L^{-1}T^{-2}**

SI unit of Pressure is Nm^{-2}

**Note – Stress also has the same dimensional formula**

Thanks a lot. Very helpful.

it helps me a lotz

Helps me a lot. Thank you very much.

Thank you . it is very useful.

I was using pressure as (mass/Area) instead of (Force/Area), resulting a wrong answer. Now it’s okay. thank you

Great site.

Thanks ðŸ™‚

Thank u so much for providing these useful info. It helped me to complete my homework.

i was seriously confused i used google to get here and thank goodness i did find this site very helpfull lots of thanks

Problem solved thanks to this site

Can I get some help? I can’t understand why is it ML-1T-2 and not ML-2T-2???? Shouldn’t the L be to the power of negative 2 because It was a denominator to the power of two and we should add a negative to it as we remove the fraction??? If you have any Info or advice, I would love to hear.=

Thanx

Is this same for pressure difference

thanks a lotz

It is very good website

Thanks it’s really helpful

its help us to do science activities in different factor of science in engineering

Thank u very much for helping me…

The formula’s are easy to understand.Thank you

thnks alot

Pressure and stress dimensional formula sem

Yes Amrita Dimensional formula of pressure and stress are same.

Thanks

is it same for pressure difference

Very Nice

Very helpful for student …

Thanks

Thanks for this
