Only if... (a) you know the weight of a measured amount of tarmac - and (b) you know what depth the tarmac is. If you can calculate the volume of tarmac, and you know the weight of a specific amount - you can convert to tonnes.
Metre is already a metric unit. If you mean metric tonnes to metres divide by a million, i.e. 1,000,000
Tonnes divided by 1,000 = kg
1 tonne = 1,000,000 grams
To convert from kilograms to tonnes, divide by 1000.
Without more information you cannot.
The conversion depends on the density of the tarmac. The density of tarmac typically ranges from 2 to 2.4 tons per cubic meter. Therefore, 1 cubic meter of tarmac would weigh between 2 to 2.4 tons.
2.4 tonnes/cubic meter
Metre is already a metric unit. If you mean metric tonnes to metres divide by a million, i.e. 1,000,000
1 Zetta Tonne = 1,000,000,000,000,000,000,000 Tonnes, that's 21 0's
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).
1.75 tonnes 1,750 kg of ballast is one cubic metre, if its concrete then you'd need to add 300kg of cement to mix this to the right ratio for a foundation.
35,000 pounds = about 15.9 tonnes. (divide pounds by 2,204.6 to get tonnes)
Tonnes divided by 1,000 = kg
1 tonne = 1,000,000 grams
kg divided by 1,000 = tonnes
European convert: 1 tonne = 1000 kg = 2000 pound US convert: 1 short ton = 2000 pound UK convert: 1 long ton = 2240 pound
To convert tonnes to billion cubic meters (bcm) for natural gas: Determine the specific gravity of the gas in cubic meters per tonne. Multiply the number of tonnes by the specific gravity to obtain the volume in cubic meters. Divide the result by 1,000,000,000 to convert cubic meters to bcm.
