🌡️ Pressure Tips
- • At sea level, atmospheric pressure is approximately 14.7 PSI / 1 atm
- • Car tires are typically inflated to 30–35 PSI
- • Always check tire pressure when cold for accurate readings
- • Blood pressure is typically measured in mmHg (normal: 120/80 mmHg)
- • SCUBA diving pressure increases by 1 atm for every 10 meters of depth
