What metric unit would you use to measure the weight of a grasshopper?

Answer 1

It depends on what characteristic of the grassshoper you want to measure - its mass, its length, the volume of its chirp, the frequency of its colour. etc.

To ad to the above by giving the scientifically appropriate units, and in that order, they are:

'

For mass, the gramme (g),

'

For length, the millimetre (mm)

'

For chirp volume, the "deciBel re 20micro-Pascals" or 20dB re 20µPa for short.

(This is often called just the 'deciBel' for shortness, provided the context is clear, as the decibel is a logarithm of a ratio, not a linear unit of a single thing like the gramme or millimetre. It is the standard unit for airborne sounds, related to the 0dB set at the 20 micro-Pascals minimum sound pressure-level audible to humans with fully-healthy hearing. If you calculate our 0dB pressure's linear equivalent, it is a staggeringly tiny 1 / 5000 000 000 of 1 Atmosphere! Don't say you didn't ask... :-) )

'

Frequency of chirp: Hertz (Hz)

'

Frequency of colour: possibly Hz but light is more often measured in wavelength instead, when it would be the nanometre (nm), where 1nm = 1 X 10^(-9) metres. I am not sure on this point but the choice may reflect (!) the SI definition of the Metre as so-many wavelengths of sodium light; bright yellow, in the middle of our visible spectrum.

'

What else?

Walking or flying speed? Metres/second (m/s, sometimes expressed as m.s^(-1) ).

Pity this text editor doesn't include superscripts to allow typing such units properly, so clearly!

Answer 2

You would use the gram to measure the weight of a grasshopper

Answer 3

Grams for weight, millimeters for length and width.

Answer 4

It depends on what characteristic of the grassshoper you want to measure - its mass, its length, the volume of its chirp, the frequency of its colour. etc.
