The volume of the rod is 100 cm* pi*(0.95 cm)^2 . The units will be cm^3.
Its mass in grams then is that volume*density of the steel (in g/cm^3).

JUST IN CASE................
If you know the density of the steel and you calculate the volume of your steel rod then you can calculate the MASS of the steel rod.
I know 'weight' is used in everyday speech for MASS but if you have been set a technical problem you might really want to know the WEIGHT.
WEIGHT = MASS x acceleration due to gravity (g). G is often taken as 9.8 metres per s per s. Mass has to be in kg and the units of weight are newtons or N.
If you are expected to be really precise then you will have to use the value for g corresponding to where you are in the world.

Pretty close to 2.25 kilograms, or a half ounce under 5 pounds, using an industry standard average for the density of steel. Any particular specimen could differ by up to 0.05 kilograms or two ounces.

Weld is the terrific, for potential. you additionally can braize them at the same time, resembling welding, yet you prefer a torch setup. i'm uncertain you are able to desire to apply solder on the steel rods, it does no longer carry. possibly you are able to desire to apply a brass coupler or a "TEE" installation like in plumbing or electric powered conduit, and you are able to have 3 products with the TEE installation interior the midsection. in case you do weld them, it rather is terrific to 'saddle' one onto the different, and weld around in a helix. Grind one end out to style a saddle and in great condition into the a million/8 rod.

you know the volume (transformed accordingly), you need to know the density of the steel. Than you can find out the mass=density*volume. If you want the weight than you will find it with the formula weight=mass*gr_acc where gr_acc= gravitational acceleration which is approximatly 9.81 (if you want a more precise result, you should indeed check the value of your position on the globe).

19 MM is about 3/4 in & 3 meters is about 3 ft so 3meters should weigh about 4.512 pounds + /- .5 pounds for 1018 cold rooled steel which different metals vary by density

i think ure 1mtr of 19mm steel will weigh 2.25kg

not if you dont tell me what type of steel it is.
once you know the type of steel it should be pretty easy to find the density. i'll tell you the equation for weight once you know the density
(pi/4)*(0.019)*(0.019)*(1)*density = your answer in kg.

well no, steel is an alloy, you would have to know the exact composition of the steel before you could work that out.
