So assuming I want 650 kilograms in total, how many more pounds or kilograms do I need to purchase and how much will it cost me?

Let’s do the math step by step:

1. Your Current Weight Total

You said you already have 1000 lb, which we converted earlier to:

  • ≈ 453.6 kg

2. Your Target Total

Your goal is:

  • 650 kg total

3. Additional Weight Needed

Additional kilograms needed:

  • 650 − 453.6 = 196.4 \, \text{kg}

Convert that back to pounds (1 kg = 2.20462 lb):

  • 196.4 × 2.20462 ≈ 433.1 \, \text{lb}

✅ You need ≈ 196.4 kg (≈ 433 lb) more weight.

4. Cost Calculation for Each Option

Option A – 45 lb Cast Iron Plate

  • Price per pound = $2.00 (from our earlier calculation)
  • Total cost = 433.1 × 2.00 ≈ \$866.20

Option B – 50 kg Calibrated Steel Plate

  • Price per kg = $5.10
  • Total cost = 196.4 × 5.10 ≈ \$1,002.64

5. Conclusion

💰 Cheapest Choice (for just weight):

45 lb Cast Iron Plates – about $866 to reach 650 kg total weight.

🏋️ Premium Choice (competition-calibrated):

50 kg Calibrated Plates – about $1,003 to reach 650 kg total.

Would you like me to figure out the exact number of plates you’d need (e.g., how many 45 lb plates or 50 kg plates to buy) to hit 650 kg as closely as possible? That way you’d know precisely what to add to cart.
