❄️ Capacity: The Heart of HVAC

Most HVAC conversions revolve around cooling and heating capacity. The key is to anchor all calculations to BTU/hr — the industry’s standard unit.

• 1 Ton = 12,000 BTU/hr

  For quick checks, remember this “magic number.”

• 1 kW ≈ 3,412 BTU/hr

  Convert BTUs to electrical capacity.

• 1 HP ≈ 0.7457 kW

  Useful for compressors and motor sizing.

Keywords: BTU/hr, Ton Refrigeration, kW, HP, Compressor Sizing

⚡ Electrical Safety & Load Calculations

For electricians and HVAC technicians, accurate electrical conversions prevent overloading and component failure.

⚙️ Ampere to kW Conversion

Formula:

$$P = I \times V \times PF$$

Where:

• P = Power (kW)

• I = Current (Amps)

• V = Voltage

• PF = Power Factor (usually 0.85 for single-phase)

🔋 Capacitor and Resistance

• 1 F = 1,000,000 μF — commonly used in AC capacitor ratings.

• Use Ohm’s Law for quick checks on motors and resistors:

  $$V = I \times R$$

Keywords: Ampere (A), Kilowatt (kW), Power Factor (PF), Capacitor, Ohm (Ω)

🌡️ Pressure, Temperature & Air Velocity

Technicians frequently measure static pressure, temperature differentials, and air velocity on site.

Pressure Conversion

• 1 PSI ≈ 6,895 Pa (Pascals)

• 1 BAR = 14.5 PSI

Use these for refrigerant gauges, pumps, or air ducts.

Temperature Difference (ΔT)

• Δ°F = Δ°C × 1.8

  Important when checking coil performance or system efficiency.

Air Velocity & Airflow

• 1 FPM ≈ 0.005 MPS

• CFM ⇆ CMH — used in fan performance and duct design.

Keywords: PSI, BAR, Pascal, CFM, FPM, Delta T (ΔT), Air Velocity

🧠 Pro Tip: Build Muscle Memory

Don’t rely solely on calculators — memorize key conversions:

• 1 Ton = 12,000 BTU/hr

• 1 HP = 0.7457 kW

• 1 PSI = 6,895 Pa

• 1°F change = 1.8°C change

This will speed up your diagnostics and make you more confident during service calls.
