3 grams of silver per kilogram of sugar

Historical Silver Prices
1 oz of gold = 15.1 oz of silver --> 28.3495 gram of gold = 428.0778 grams of silver --> (428.0778/28.3495=15.1) --> 1 gram of gold = 15.1 gram of silver

Historical Gold Prices: 30 BCE to Today
1664: 4.05 £ = 1 gram of gold

So, 4.05 £ = 1 gram of gold = 15.1 grams of silver = 5.03 kg of sugar
So, 1 £ = 1.24 kg of sugar or 1 kg of sugar = 0.8 £ (1700s) :

Currency converter: 1270 - 2017
£106.98 (2017) = £1 (1700)
£85.584 (2017) = 0.8 (1700) = £98.95 (2022) = 4,277.45 Thai Baht (2022) = 16,336.30 Japanese Yen

Summary: 1 kg of sugar = 4,277.45 THB
