You can't convert that. You can only convert units that measure the same type of thing - for example, units of length to units of length, units of mass to units of mass, units of time to units of time, etc.
You can't convert between units of length and units of area.
You don't. The two are completely incompatible units.
This is not a valid conversion. Cubic units is a measure of volume while square units is a measure of area.
A tonne is a unit of mass; a square meter is a unit of area. You only "convert" units of the same kind.

You cannot. The units are incompatible.

A tonne is a unit of mass; a square meter is a unit of area. You only "convert" units of the same kind.
You can't convert between square units and linear units.
Feet and square meters are incompatible units - a foot or a meter is a unit of length, a square foot or a square meter are units of area. You can't convert them.
It doesn't make sense to convert units that measure completely different things. You can only convert units of length to units of length, units of mass to units of mass, etc.
You can't convert that. Hectoliter, and liter, are units of volume; meter is a unit of length. You might, however, convert hectoliters to CUBIC meters.
Which following? SI units are the meter, the Celsius, the kilogram, the candela, the Pascal, the joule and the ampere.
You can not convert between units of length (like meter) and units of volume (like liters).
