• 1ha in m² 1ha = 10.000m²
• 1a in m² 1a = 100m²
• 1 m² in cm² 1m² = 10.000cm²
• 1l ind dm³ 1l = 1dm³
• 1l in ml 1l = 1.000ml
• 1m³ in dm³ 1m³ = 1.000dm³ (= 1.000l)
• 1m in cm 1m = 100cm
• 1m³ in cm³ 1m³ = 1.000.000cm³
• 1m in dm 1m = 10dm
• Kreisformel A= r² x π
• Dreieckformel A = g x h /2
• 35¤ 100% ?? 7% 7% x 35€ / 100 = 2,45€
• spritzmittel 200l/m² Düngemittel 4% Fläche 4 ha 1 ha = 10.000m² 4ha = 40.000m² 40.000m² x 200l = 8.000.000l 8.000.000 x 4% / 100% = 320.000l ergebnis: 8.000.000l SP und 320.000l DM
• Fläche: 40mx15m Sp: 30l/m² Dm:5ml/m² oder 5ml/l.sp 40 x 15 = 600m² 600m² x 30l = 18.000l 600m² x 5ml = 3.000ml = 3l 18.000l x 0,005 = 90l
