做了个狗龄计算器，才发现"1 狗年 = 7 人年"是错的 家里养了只金毛，一直按"狗 1 岁 = 人 7 岁"算，后来查资料发现这个公式根本不科学——狗的第一年其实相当于人的 15 岁左右，而且不同体型的狗衰老速度差很远。 于是做了个工具：dogyearcalc.com ( https://dogyearcalc.com/) 它做了什么： - 内置 4 种计算公式：AKC 体型公式、UC Davis 表观遗传时钟（测 DNA 甲基化得出的）、Standard 方法、以及那个不科学的 Classic 7x 方法（留着做对比） - 支持 386+ 犬种的品种特异性计算，大型犬和小型犬的衰老曲线完全不同 - 多狗对比模式——家里养了两只以上的可以并排看 - 生命阶段可视化 + 当前阶段的健康建议 - 8 种语言（中英日韩德西法葡） 技术方面： 纯静态站，HTML + CSS + 原生 JS ，部署在 Cloudflare Pages 。没有框架，没有注册，加载速度 89ms 。计算全部前端完成，不收集任何数据。 想听听大家的意见： 1.

Got curious what a pointless meeting actually costs me, ended up building wage calculator www.wagescalc.com I was sitting in a meeting that should have been an email and wondered what that hour was literally costing me in wages. Turns out about $29. Then I wanted to know the per-minute number. Then per second. So it's a salary-to-hourly converter. There's a meter at the top that starts counting the second the page loads and shows what you've earned since you opened it. Leave the tab op

做了一个海外 TikTok 直播打赏收益的计算器 大家好，最近关注到海外 TikTok 直播打赏很火，很多主播正在靠直播礼物默默赚钱。不过观众花了多少钱、平台抽走多少、主播实际能拿到多少，计算起来并不直观。 所以我做了一个 TikTok Coin 收益计算工具。 地址： https://coinvaluecalc.com/ 这是什么？ TikTok 观众先购买 Coins ，再用 Coins 给主播赠送礼物；主播收到礼物后，会获得对应的 Diamonds , 再用 Diamonds 转化为收益。 工具输入 Coins 数量，工具就能估算观众的购买成本、TikTok 平台费用，以及主播最终可以获得的收入。 特点： ✅ Coins 、Diamonds 和美元快速换算 ✅ 区分观众花费与主播收益 ✅ 收录常见 TikTok 直播礼物 ✅ 完全免费，无需注册，即开即用 不同地区和充值渠道的价格可能不同，计算结果仅供参考。欢迎大家体验和提建议。
