You would measure a fern in meters, or if it is small, perhaps in centimeters. Ferns come in very different sizes.

In the SI, energy is measured in Joules.Some other units (not part of the SI) include: erg; BTU; calores; and others.In the SI, energy is measured in Joules.Some other units (not part of the SI) include: erg; BTU; calores; and others.In the SI, energy is measured in Joules.Some other units (not part of the SI) include: erg; BTU; calores; and others.In the SI, energy is measured in Joules.Some other units (not part of the SI) include: erg; BTU; calores; and others.
Meter per secondThere is no standard SI unit for velocity actually. It is a derived unit. Velocity is distance traveled per time together with the direction of motion. The SI unit of distance is the meter (m) and the SI unit of time is the second (s).So the units of velocity in SI units is meters/second (m/s), or ms-1See the Related Questions link to the left "What are all the SI units" for more information about SI units.CommentDerived units are SI units.
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
The SI unit of temperature is the Kelvin. It's the same size as the Celsius degree.
You may not have any units. Standard units are not used in data on household size, for example.

Instument: a balance, a scale, of any size Units: depending on size either a gram or a kilogram if you are using scientific terms (SI units).........a pound in American Standard Units.
SI units are more accurate than English system units
The SI has 7 base units. These units can be combined in an almost unlimited way to form other (derived) units. The Wikipedia article on "SI derived units" lists some examples.
