Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

Planck units

Please see here for Planck units:

http://en.wikipedia.org/wiki/Planck_units

Even though most of these are outside the range of our everyday needs, they have the advantage of being truly universal constants, they are the same everywhere in the universe.

So, I suggest to include

Planck mass m_P = 2.17645E-8 kg on the "mass and weight" page,

Planck length l_P = 1.61624E-35 m on the "distance and length" page,

Planck volume l_P³ = 4.22199E-105m³ on the "capacity and volume" page,

Planck area l_P² = 2.61223E-70 m² on the "area" page,

lightspeed is on the "speed" page anyway (good!)

Planck temperature T_P = 1.41679E+32 K on the "temperature" page,

Planck time t_P = 5.39121E-44 s on the "time" page,

Planck pressure p_P = 4.63309E+113 Pa on the "pressure" page,

Planck energy E_P = 1.9561E+9 J on the "energy and work" page,

Planck power P_P = 3.62831E+52 W on the "power" page,

Planck torque M_P = 1.95609E+9 Nm on the "torque" page,

One could even construe a "Planck fuel consumption", which would be a relation between the fuel consumed (in units of Planck volume) and the distance travelled (in units of Planck length). I guess that would get you to the limits of internal floating-point math :)

Have a good work! toby
