Measurements

Examples:

Current conditions at depth: Temperature 2C/35F, Depth -5000m/16400ft,  Pressure 497 atm, Current NE 34 Sv.

Current conditions on island: Temperature 29C/85F, Elevation +3m/10 ft, Pressure 1 atm, wind SSW 2.6kn/4.8kph/3mph. Partly cloudy.

Mircon Measurements:

I am working on Mircon measurements and may add them in dialog but not in the current conditions. Mircon degrees are 5(C+3) and abbreviated MT. Pressure is MP and 1 mp = 27.4 atm. Major depth is measured in MD units - 1 MD ~= 875 ft or 267 m, this is about how often we will stop on descent (ascent we will use the computer). Currents are measured in MC which are about 8 Sv.

Less familiar measurements I will be using:

Sverdrup (Sv) - oceanic current measure. Equivalent to 0.001 km³/s or 264 million gal/s. This I will make up randomly for effect.

Knots (kn) - 1 nautical mile/hr or 1.852 kph - for boat speed, swim speed, and windspeed. I will make this up as well.

Atmospheres (atm) = 101,325 Pa, if you think in bars better it is 1.013 25 bar. It's an old unit, but Descubralian divers use it still. It is also 14.696 psi. Most of our trip will be 398 atm or greater. I have a depth-atm converter.

Other measurements and how I will abbreviate them:

Fahrenheit (F), Celsius (C) - expect temperatures in the 2-3C/35-37F range

kilometers per hour (kph - km/h messes with my slashy system), miles per hour (mph) - to help those of you who don't think in knots

Feet/meters above/below sea level (above: +ft/m, below -ft/m) - This matters because for safety reasons, and because Abyssal Mircon think dive tables are over-complicated, we will pause for a time every time the little computer beeps - decompression stops. If one person's species or air mix requires them to stop more often, the computer will be set for that. (in short, because I can't read dive tables, and I can't find any for below 140 feet because humans cannot currently dive that deep, I will randomly have us stop for good measure).

Less likely units:

cubic kilometers per second (km³/s) and millions of US gallons per second (Mgal/s) - these I will only use if the Sv really matter to you and confuse you.

pounds per square inch (psi), bars, Pascals (Pa)- Only to explain atm.
