NONE! A kilometer, symbol km) is a unit of length in the metric system. A liter is a unit of volume in the metric system. They are totally different.
Ontario gas prices changed to metric in 1976. At that time, the province transitioned from using gallons to liters for fuel pricing, aligning with Canada's broader move towards the metric system. This change was part of a nationwide effort to standardize measurements across various sectors.
Matter is defined as that which has mass and occupies space. There are procedures to measure both. Even if you can't measure the mass of an object directly (such as a gas), you can still determine it's mass by measuring the space it occupies. Pressure is one way to measure the mass of gas by the amount of space it occupies.
In a country which uses the Metric System (as most do), yes.
There are no specific states that use only the metric system, however on most things that are relevant (gas and food mostly), there are multiple readings, the metric is generally slightly smaller though. If you are referring to science then the metric system is always used.
The answer depends on the context in which the word "state" is used. If you mean the state of matter, there is no difference between the metric and the ancient system. In either system a gas is a gas gas gas (as JJF might say)!If by state, you mean a geopolitical region, the answer will then depend on what characteristic of the state you wish to measure: most economic measures would not be metric. Mean altitude would be measured in metres (above mean sea level), are on square kilometres, and so on.
if the m stands for cubed which it usually does, then yes, the metre cubed is a metric measurement
Litres
That would be U.S. gallons ( In Canada they use the metric system now which is liters instead of the Imperial gallon which was 20 % larger than the U.S. gallon ) 18.5 U.S. gallons is roughly 70 liters
Well there are two ways in the metric system Liters and cubic meters take your pick and the volume can be found from the equation below. (PV= MRT) or (Pressure) * (Volume) = (Molar Mass of Gas) * (R constant) * (Temperature of gas)
1 metric ton of natural gas typically produces approximately 0.65 to 0.7 metric tons of urea.
1 mile is hard to show but i know that in Canada u know the place that uses the metric system not like the us who are a little slow in changing over but i use 70l for every 350-400km depending on hills and speed and so on
