Calculate SaaS Quick Ratio from new, expansion, reactivation, churned, and contraction MRR.
WHR = waist circumference / hip circumference. Measure waist at the narrowest point (above belly button) and hips at the widest point (around buttocks).
Men: low risk (<0.90), moderate (0.90-0.99), high (1.00+). Women: low risk (<0.80), moderate (0.80-0.84), high (0.85+). Higher WHR indicates greater cardiovascular and diabetes risk.
WHR measures fat distribution (apple vs pear shape). BMI measures overall weight relative to height. WHR is a better predictor of cardiovascular risk than BMI alone.
The ratio is the same regardless of unit. Use whichever measuring tape you have — the WHR value is unit-agnostic.
