The Planet Crafter Terraformation Calculator

Pick a planet, add your machines, fuses and rockets, and see oxygen, heat, pressure and biomass per second, the total Ti per second and how long the next stage takes.

Rockets launched

Each rocket multiplies the whole planet's output of one unit. Rockets of the same unit add up.

Seed spreader rocket+10× Oxygen each
T2 Oxygen Rocket+60× Oxygen each
Asteroid attraction rocket+10× Heat each
T2 Asteroid attraction rocket+60× Heat each
Magnetic field protection rocket+10× Pressure each
T2 Magnetic field protection rocket+60× Pressure each
Plant Rocket+12.5× Plants each
T2 Plant Rocket+60× Plants each
Insect spreader rocket+15× Insects each
T2 Insect spreader rocket+60× Insects each
Animals spreader rocket+17.5× Animals each
Purification rocket+10× Purification each

Your current values (optional)

For the time to the next stage. Type numbers as the game shows them in its base unit, or with k, M, G, T, P, E (1.5G = 1,500,000,000). Ti is the sum of the parts; a typed Ti total wins.

How the Ti per second is counted

The game adds up the per-second gain of oxygen, heat, pressure and biomass (plants, insects and animals together); Purification joins once its level is above 0. Ti per second is that plain sum, and the stages on each planet are thresholds on the running Ti total, as stored in the game files.

A fuse or a seed, larva or egg held in a machine adds to that one machine's multiplier and replaces the base 1. A rocket multiplies the whole planet's output of one unit. Machines are counted fully powered, and the rate is taken as constant, so the time to a stage is an estimate: build more and it drops.

The files do not say how many machines one fuse reaches or which machine takes which seed, so you set both yourself. Numbers are read from the game files, build 2.103. See the planets and stages, the structures and the crafting calculator.
