1. Unit Conversion Accuracy
SandSpan uses conversion factors sourced from internationally recognized standards including the International System of Units (SI), the National Institute of Standards and Technology (NIST), and ASHRAE standards for HVAC-related conversions. Despite our best efforts to maintain accuracy, we make no warranties about the completeness, accuracy, or reliability of any conversion result.
- Users should verify critical conversions against primary reference sources.
- For safety-critical or regulated professional applications, always consult a qualified professional.
- Certain conversions — such as calendar-based time units or empirical formulas (e.g., Saybolt Universal Seconds) — inherently involve rounding and approximation.
2. HVAC Energy Cost Calculator
The HVAC Energy Cost Calculator provides estimates based on user-input parameters including unit size, SEER rating, electricity rates, and usage hours. Actual energy costs may differ significantly due to:
- Local climate conditions and seasonal temperature variations
- Home insulation quality, window efficiency, and air leakage
- Thermostat settings and actual usage patterns
- Ductwork condition and system maintenance
- Utility rate structures including time-of-use pricing and tiered rates
For a professional energy audit, consult a licensed HVAC technician or certified energy auditor.
3. Construction Material Calculator
The Construction Material Calculator provides estimates for concrete volume, brick quantities, paint coverage, and lumber requirements. These estimates are for planning purposes only and may not reflect:
- Material waste from cuts, breakage, or spillage (always add 5–10% extra)
- Local building code requirements for specific materials or dimensions
- Site-specific conditions such as uneven ground or non-standard wall construction
- Variations in material specifications between manufacturers
Always consult a licensed contractor or structural engineer for project-specific material estimates, especially for load-bearing structures.
4. Medical Dosage Converter
- Medication concentrations vary by manufacturer — always verify against the actual medication label.
- Pediatric dosing requires consideration of the child's specific condition, organ function, and concurrent medications.
- Insulin concentration errors can cause life-threatening hypoglycemia or hyperglycemia.
- IV drip rates must be verified by a licensed healthcare professional before administration.
- If you have a medical emergency, call your local emergency services immediately.
