Satuans
Math Notepad supports units. Satuans can be used in basic arithmetic
operations like add and subtract, and units can be converted from
one to another.
All available units are listed in the table below.
| Basis |
Satuan |
| Panjang |
meter (m), inch (in), foot (ft), yard (yd), mile (mi), link (li), rod (rd), chain (ch), angstrom, mil |
| Luas |
m2, sqin, sqft, sqyd, sqmi, sqrd, sqch, sqmil |
| Volume |

| Liquid volume |
minim (min), fluiddram (fldr), fluidounce (floz), gill (gi), cup (cp), pint (pt), quart (qt), gallon (gal), beerbarrel (bbl), oilbarrel (obl), hogshead, drop (gtt) |
Waktu

rad, deg, grad, cycle |
| Waktu |
second (s), seconds, minute (minutes), hour (h, hours), day (days) |
| Massa |
gram(g), tonne, ton, grain (gr), dram(dr), ounce (oz), poundmass (lbm, lb, lbs), hundredweight (cwt), stick, stone |
| Electric current |
ampere (A) |
| Temperature |

| Amount of substance |
mole (mol) |
| Luminous intensity |
candela (cd) |
| Force |
newton (N), dyne (dyn), poundforce (lbf) |
| Energy |
joule (J), erg, Wh, BTU, electronvolt (eV) |

Note that all relevant units can also be written in plural form, for example 5 meters instead of 5 meter or 10 seconds instead of 10 second.
Luas and volume units can alternatively be expressed in terms of length units raised to a power, for example 100 in^2 instead of 100 sqin.
