Units and Conversions
SI base, derived, and common chemistry conversions. All conversions preserve dimensional consistency.
| Quantity | Unit | Symbol |
|---|---|---|
| Amount | mole | mol |
| Mass | kilogram | kg |
| Length | meter | m |
| Temperature | kelvin | K |
| Time | second | s |
| From | To | Multiply by | Dimensional check |
|---|---|---|---|
| g | kg | ÷1000 | M |
| mL | L | ÷1000 | L³ |
| atm | Pa | ×101325 | M·L⁻¹·T⁻² |
| °C (ΔT) | K (ΔT) | same magnitude | Θ |
| °C (value) | K (value) | T(K)=T(°C)+273.15 | Θ |
| L·atm | J | ×101.325 | M·L²·T⁻² |
Temperature for gas and energy equations must be in kelvins. Use factor-label (dimensional analysis) to check each step.
