sin (90 degrees) = 1
When mixing plain numbers with units, the nearest unit will be used automatically. This is called unit assimilation.
300 + 20 km | 320 km$20 + 30 | $50.00
When doing calculations with mixed unit types, last unit wins:
1000 m + 1 km | 2 km$200 + €200 | €323.85
Soulver only uses units that it knows about:
10m × 10m | 100 m² // a supported unit3 kg × 3 liters | // Soulver will not give you "9 kg liters" here
Soulver will instead make an implicit rate when a supported unit cannot be created through multiplication:
$30 × 4 days | $120.00// the above is interpreted as $30/day × 4 days
Soulver will use a unit's symbol in the answer, rather than its full name. Though you may use the full name in your expression:
10 kilometers in meters | 10,000 m20 tablespoons in teaspoons | 60 tsp
You can add additional units to Soulver in the "Tweak Calculator" sheet (click the cog in the top right corner) > Custom Units.
Custom units must be defined in terms of another supported unit. Creating new base unit types is not currently supported.
