The time has come to finally put aside the uncertain definitions of volumes, lengths and times based on uncoordinated reference standards. From these early years of the 21st Century, while keeping the quaint names our glorious language provides, we must express these definition in terms of a standard defined in terms of invariant constants of nature:

1. Metre - the length of the path travelled by light in vacuum during a time interval of 1/299792458 second.

2. Kilogram - the mass of 1 dm^3 of water under atmospheric pressure and at the temperature of its maximum density, which is approximately 4 °C

There has been some work carried out to accurately define the volumes in metric term of some terms such as:

Tad = 1/4 teaspoon = 1.25ml

Dash = 1/8 teaspoon = 0.625ml

Pinch = 1/16 teaspoon = 0.3125ml

Smidgen* = 1/32 teaspoon = 0.15625ml

Drop = 1/64 teaspoon = 0.078125ml

However there is work to be done in defining the metric equivalents of these measurement terms:

1. A poofteenth

2. A bee's dick

3. A hair

4. A gnat's nut

5. A coat of varnish.

Please help us to identify, name and quantify the ancient names for daily measurements so that they can be metricated for future generations.
