To convert steam tonnes to megajoules, you first need to know the energy content of steam. Generally, 1 tonne of steam (at 100°C) contains approximately 2,260 megajoules (MJ) of energy, which is the latent heat of vaporization. Therefore, you can multiply the number of steam tonnes by 2,260 MJ to get the total energy in megajoules. For example, 5 steam tonnes would be 5 x 2,260 MJ = 11,300 MJ.
Those units are unrelated, and uncompatible - can't be converted. Grams / hour has units of mass / time. Joules or megajoules is a unit of energy.
Tonnes divided by 1,000 = kg
1 tonne = 1,000,000 grams
Without more information you cannot.
To convert from kilograms to tonnes, divide by 1000.
To convert ton miles to megajoules, you would need to know the efficiency of the conversion process. Without this information, it is not possible to provide an accurate conversion.
1 Zetta Tonne = 1,000,000,000,000,000,000,000 Tonnes, that's 21 0's
Those units are unrelated, and uncompatible - can't be converted. Grams / hour has units of mass / time. Joules or megajoules is a unit of energy.
To convert cubic meters to tonnes, you need to know the density of the material you are measuring. Multiply the volume in cubic meters by the density in tonnes per cubic meter to get the weight in tonnes. The formula is: weight (tonnes) = volume (cubic meters) * density (tonnes per cubic meter).
quantity of steam generated in a boiler is usually measured in TPH ie tonnes per hour
You have to consult tables which give the properties of water and steam (commonly called Steam Tables). You have to calculate the total enthalpy of the steam as delivered, and subtract the enthalpy of the returned condensate (if returned) or of the water as it enters the boiler. In modern steam tables this will be in kilojoules per kilogram. You can multiply by mass to get total energy. To convert to kilowatt-hours, note that 1 kWh = 3.6 MJ. Various organizations have published steam tables in the past. The one published by the International Association for the Properties of Water and Steam is the one to use, particularly the 1997 formulation for industrial application. There are some free caclulators online which claim compliance to the algorithms, but I can't vouch for any of them. It is not straightforward and you may want the services of a competent steam engineer (that leaves me out. I may be able to hack my way through, but I am not "qualified" in this area.)
To convert ton miles to megajoules, you would need to know the specific energy consumption rate of the transportation method used to move the 1000 tons over the distance in miles. Once you have this rate, you can multiply it by 1000 ton miles to get the energy in megajoules.
35,000 pounds = about 15.9 tonnes. (divide pounds by 2,204.6 to get tonnes)
European convert: 1 tonne = 1000 kg = 2000 pound US convert: 1 short ton = 2000 pound UK convert: 1 long ton = 2240 pound
Tonnes divided by 1,000 = kg
1 tonne = 1,000,000 grams
kg divided by 1,000 = tonnes
